HELPPP please...

i had 2 bluecheese and 4 shaman and 2 churches and they are ALL dead, except this bluecheese which is on the way.

I really cant figure out what is wrong with them .

a week or so ago it was fine n all and now its half dead.

im growing in 1cm RC cubes under a 250 metal halide, air circulation is good and temp is between 22-24c.

A+B iconic @ 1/2 strength,
oxy-plus - 10ml/day {tank is 20L}
nytrozyme - {as directed on the bottle}
gurdian angel - {as directed on the bottle}
superthrive - {couple of drops in tank}
canna trichoderma. foiler feed 2-3 times per week

the rest of the plants died befor i started adding nytrozyme, guardian angel, superthrive, and trichoderma to the tank so i guess they have nuthing to do with it.

this bluecheese was the youngest one of the lot as i added it round 2 weeks later than the others and it was holding up. till a couple of days ago.

i strated off flooding 1x a day, moved up to 2x and now i have dropped it down to once a day.
========

lower {older i think} leaves start to yellow from outside and work their way all over, and it happens rappidly over a couple of days, then the ones above them start to do the same and now i can see that even the top are starting to yellow on the edges tho its very slight.
the plant has not grown at all for about a week, since the lower ones started yellowing.


the yellowing is really bad on the lower ones.
stems are dark purple which i think is just normal.
i have already removed 2 lower leaves as they just got tooo yellow and they were the biggest leaves on the whole thing.


i have no idea what to do please help.
iv flushed it today with superthrive/guardian angel and about 1/3 strength nutes to see what happes.

any suggestions or ideas please, need help fast.

i hope iv filled it out properly. but iv got all the information at the top anyway. pleasee help.

its almost dead but i wanna make sure that it doesnt happen again or at least find out what it is, i suspect it is nitrogen def. but dont know how to cure.
and all the plants get to the same stage very healthy and very good and then start the same pattern and die off the same way .
and iv just calculated iv gone thru around 20 plants now .

filled out the form, they cant possibly be thirsty tho. i feed them once a day, and at points was feeding twice, til i noticed they were a lil droopy.

oh n the way i feed them is kinda like flood and drain, i dip them in a nutrient tank for about a min or 2, wait till the water mostly drains out over the tank, n then move them back to their place where they can drain the left over while sitting.

When you foiler feed 2-3 times per week is it during light hours ? It should be at dark.
I never foiler feed till recently and I killed everything, about 20. Only did it a few times and things looked great. Then bam all started to turn just like yours.

Also had a cold blast on hydro water and they turned yellow almost over night.

The other thing is ventilation ? Are the getting fresh air or just push around air ?

Your not getting them enough water most likely. Do the ebb and flow or you could drip back to rez But they need more water. I run drip 130gph pump wide open on 6 plants 24/7. Those rocks do not hold water like hydrtron or all rockwool.

yea when i was foiler feeding i did it under light, tho there was no heat problem therfor i dont think it was a problem tho i remember the leaves got a bit paper like but after a while got back to soft.
how did urs die, did they keep getting yellow till eventually they look like they shrunk real bad?

ventilation is good i say because they are in a built in closet and the door from the other side is always open, therfor air comes into the closet from the side and the hot air gets pushed out thru the top as there are holes in the uper side, so it circulates new air and not the same air, and that room is open to 3 different rooms that have open windows so air and temp are no problem, im giving them plenty water, as when i water i flood them as i have a nutrient tank/tub which i dip the whole pot {till about 80% from the stem in order to keep the top of the root dry} and then i take them out after soaking them for about 2 minutes 80% fully submerged, i was doing that 2x a day n now im doing it once as i think i was overfeeding them, i dunno man its pissin me off cuz iv lost so much and now i have the final set of about 6-7 plants which i just germd bout a couple of days ago and i have a feeling the same is gona happen.

we need a plan lool.

Are you growing in a grow tent?

If so read this Warning! Sick plants in a grow tent? read this before doing anything!

symptoms look very familiar......

If you are killing everything in your growroom, different strains, different occasions. I would guess its enviromental.

Subzero

Top leaves look very dark green, and bottom leaves dying of, and curling I would probable say nute burn...whatever volume of nute you have in your res, I would pour an extra bit of ro water in to dilute it down to like 2/3 of its original strength. And maybe even before that I would flush with 1/4 strength nutes to give it a good flushing. Good luck

lol...legalize it!

transplant into a fresh quality soil asap......no more anything except ph correct water (for soil). i'm sorrry but i do not see that plant surviving your hydro regimen which dseems to include everything but the kitchen sink and simply speed death along. transplant. And pray.

good luck

omg u just paranoid the fuck out of me, iv never heard of that shit, tho the sheeting that i had the inner closet lined with was some of that white plasicy pvc shit, and it was very old and had holes n rust in it, and i just wiped n disinfected it and put it in .
fuck it tho, i ran in the room and took the fucker off n chucked it out . i aint taking nooooooooooooooo chances loool.

thx for the bit of info if it turns out to be wt it is im gona send u a baggy by post wen the time comes

iv got no soil for one , nd on top of that this problem happend b4 i added anything, i was just feeding them on 1/2 strength n it started happenin, so it wont be ph or nutes, as ph isnt allowed to even cross 6. its always round 5.8 which is bang on.
and i even slowed the nutes down to 1/4 n still the same shit, n that was after flushing.
the extras are all top items, that are good for the plants n help out in stress. n guardian angel is for pythium as i thought that was the problem at first.

hey smooth, i already did that, and i was running about 1/2 strength and the plants b4 that, i had them runnin at 1/4 n the exact same thing happend.
its not nut burn as the leaves are not showing signes of nutburn, ie: the burn.
its showing exactly like N def or lockout.
and iv flushed n etc... same shit.

your title was please any help. that was mine. I'm sorry you seem to feel I have no clue in what iam talking about regarding growing and hydro but its YOUR half dead plant so ....... .I only enough energy for serious listeners........peace out dude goodbye

A mother plant I got from a bro of mine. Didn't look too good so I had this foliar feed spray. I mixed it light and sprayed it on every couple of days. They looked great untill. It was under fluro's and after about 6 times they started to turn yellow, shrink and fall off. Starting from the bottom to the top. I think the spray built up on the leaves. Did not think about washing them with PH water spray. After I stopped the topps barely survived and came back nice.

When I got a problem like this I go back to bare basics to try and pinpoint the problem. Your ventilation sounds good.

hey bro, from looking at the color of those bottom leaves it looks like some
kind of deficiency which means there is probably some sort of nutrient lock
out going on.

also, Weedhound was suggesting you transplant into soil, even if it means going
to the store and buying a bag, because soil is much more forgiving than hydro.

then, once you get it stable, you can always take cuts off it and try hydro again.

hydro can be very tricky to get right if you are unfamiliar with the process and
very tricky to diagnose from just pictures.

what you might try is simply dumping your res and re-filling it with ph balanced
water and a couple tablespoons of H2O2 (hydrogen peroxide) but transplanting
into some dirt is the surest way to be sure your lone plant survives, and even
that might not do it.

LOC NAR makes an excellent point, plus, they are too young for that, at 2
and a half weeks i wouldn't spray with anything but water.

Your using tap water. Do you know the PPM's of the water. Maybe too high.

What kind and where did you get your rocks ?

To be on the safe side I would try what WeedHound says about soil trans plant. They are dieing anyway. Till you figure out what it is.

um, not sure y u got upset, i simply pinpointed the problem that i had no soil, and secondly said that it couldnt have been any of the nutes as i have had this problem b4 adding any of the nutes.
so im sorry u feel as if i was lashing at u, but i wasnt, i was simply being informative on the situation so i can get an update on thoughts/conclusion and nothing else.

mmmmm, actually now that u mention it, i did spray them more than i should have i think, tho i havent sprayed them for 2-3 days, the problem seems to be stable for now, the yellowing isnt progressing as far as i can see and if it is its doing it very slowly, still looks like shit tho.

u think i should spray/clean the leaves with ph adjusted water only...?

mmmm, problem is there is no soil around where i live, the only soil avail. is from a small local store and its very low quality shit, so not sure if thats a good idea, and on the other hand, if i was able to sort out soil some how, do i just dump it in with the rockwool cube? cuz that fucker aint going nowhere its all stuck to the roots, i doubt ill be able to arrange good soil till the next day or 2.
i dumped the solution and filled with water at 5.8ph {and since i dont have hydrogen peroxide} i used oxyplus and a drop or 2 of superthrive. so will see wt happens.

thx for the thoughts everyone

tap water, at 0.54 Ms, and 7.7.7.8 ph.

if you read through my cloner thread you'll see how to deal with transplanting
from bare roots and rockwool into soil. it's not exactly like your situation but
close enough.

as to the soil you mention, it would be ok as long as you added some perlite
for drainage.

keep in mind that many people keep their mothers in soil and just flower in
hydro, with dirt, you can almost neglect them.

Widow can take 11 week to flower and I think wonderwoman is 8 weeks along with papaya. Mate the Papaya is the bomb. That is what I have 2 of my mates growing now and what I have had the past few years. Everytime I smoke it with someone new to it. I ask them did I spray enough PCP on it, LOL cause one toke too many and your in for a couch ride for sure. If you get a chance my bro likes the Hawaii x Skunk from nirvana it's a very good upside med.
