Check the pics. My big seedling's first set of true leaves is starting to curve downwards pretty hard. I dont understand why either. I've been watering like 2 times daily, and I added 1/8 concentration nutes last night (Pure Blend Pro Bloom and superthrive, I'm waiting for my Pro Grow in the mail so I figured a little something is better than none).
They are growing in Pro Mix Potting and Seedling Pro. It seemed like this single one was growing in a curved manner the whole time, whereas the other two are doing great.
The curved one has some light blackening on the tips of the cotyledons and also the underleaf is turning black. Is this fungus??
I'm using 4 CFL bulbs, totaling around 114 watts. I'm waiting to put them under a 400 watt MH. They are probably 3" from the top of the plants.
All of the bulbs are underneath one of those half spherical work-style reflectors.
I have a large fan on low blowing across the plants. The setup is too small right now to have an exhaust fan, as the intake fan blows enough air to exhaust.
The bulbs are on 24/0, and are 23, 23 , 26, and 42.
I added perilite to the soil.
The container is about 4 inches tall, about the size of one of those bathroom dixie cups (a little bigger).
The source of water is tap that has sat out a couple of nights to allow the Cl- to sediment out.
My pH meter is in the mail right now, so I have no means of checking the pH.
So far, I just added the first dose of Pure Blend Pro Bloom (like I said, waiting on the grow), which is 2-3-5 (Ca 1, Mg 0.5).
I have been watering the seedlings twice a day, in the morning and evening, enough to wet the surface. I've been checking the moisture by putting my finger nail completely in the soil, and if its moist I wouldnt water.
It is an indoor grow. The room is large, but they are concealed right now in like a tunnel of sheets that I've made cause my tent is in the mail (Sounds ghetto, but it seems to have been working for the other two). My temperatures are a consistent 74 degrees F and around 42-55% humidity.
The room has an AC unit, so that has been keeping temps in check.
I have not seen signs of insects in here.
I believe the strain is Sativa (Strawberry cough, but I got them mixed up during germination like an idiot unfortunately, I was pretty high ), and they are from seed.
Please help my baby!
