Main room grow 8 plant's, 6 strains

Well I almost out of my base nutrients and the grow store and everywhere else was sold out tell next month so I had to switch to my Jungle Juice I had left from my last grow. I have roughly 80ml left of the other stuff and I'd rather save that for my 2x2 grow that's still going. Adjusted all the lights up to make more light in the room. Now there is a good solid light amount across the room and should have to worry with any light burns or anything. Had a bit of yellowing in some of my leaves. Think it's because I was running my PPM so low before. Now that I've cranked it up a bit I hope it corrects itself. Well that's all so happy growing everyone!!!
