aeroponic grow update w/ pics
hey now,
so that blotchy yellowing on my leaves has gotten worse, in three days it has progressed from random yellow spots to lots of brown spots (see new pics) it's only happening on one of the plants (the largest one) and from my research i am pretty sure it's due to a calcium deficiency. That other plant (with minor yellowing around the edges of the leaves) seems to have a slight magnesium deficiency. So far the only nutes i've added are the pellets that came with the aerogrow unit, and i've added them as directed (i know---dumbass move) Is it possible that I have over-nuted? Any feedback on this would would be greatly appreciated.
Today I turned off the bubbles, emptied the res and tried to wash out all of those crappy pellet nutes as best i could, then refilled about 1/4 way with spring water only (about 1/4 gallon) and left the bubbles / lights off for the night. Today I am going to try to pick up some Fox Farms Grow Big to resume nute...here's my questions:
how long should I flush for?
when should I turn on the bubbles & lights?
how much water should I leave in the res while flushing?
Also, I have ordered a 250w HPS light w/ MH conversion bulb from inside sun, it should be here on friday, and I was planning on switching the lights immediately. Should I wait until the plants show improvement before switching the lights?
any and all feedback is greatly appreciated...thanks!
