Hi there. This is my first time growing, and posting to this awesome forum, even though I've been surfing random posts for almost a year now.
The included pictures were just taken moments ago, of two separate plants. I have a bubbleponics/drip hydroponic system, stabilized the PH at 5.9, and I am currently lighting the plants with a 400 watt metal halide for eighteen hours daily. For some reason, I thought I read that distilled water was the best way to go for the plants. . .
I've been mixing in one teaspoon of general hydroponics vegetative fertilizer per gallon ever since week two, when I initially noticed a small problem in the foliage. The plants are now about three weeks old and are getting worse by the minute.
After playing with the concentration of the fertilizer for a few days, hoping the problem would work itself out, I decided it was worth it to try something else. I mixed in one and a half teaspoons of the fertilizer per gallon of tap water this morning, but the leaves are still getting worse.
From the reading I've been doing these past few days the best conclusion I can make is a calcium or magnesium deficiency. . . but I don't want to add cal-mag plus to the water unless I'm sure that it will help the plants. Ahhh this is so frustrating! Any input is greatly appreciated!
