The first one was taken 2 weeks ago, they looked pretty good. The second one was taken about 2 or 3 days ago, I'm pretty sure it's showing me a cal/mag def. The last three are the same plants from pic one, taken today. They are under a different light, but same schedule for now. It occurred to me what I might be seeing here; is this what happens when you pinch the tops instead of cutting them? I did a pretty reckless hack job of a topping about 4 days ago and maybe that's why these leaves are all mangled now. Silly me. Other then that, think everything seems ok?

ppm is about 900 right now, ph about 5.8 and I water them about every 8 hours. I just started adding 5ml of cal mag per gallon, today.

I'll take some better pics tomorrow when the lights turn out.
