Hey guys, I have a couple grows under my belt, things like this happen sometimes but its about 4 weeks and a day and I have 2 autoflower plants in my res, recently (usually always around the preflower time) I get some brown spots on my leaves and some of them get this very light yellow color with some brown in it. I trimmed the leaves in the pics off the two different plants, is it a cal-mag/potassium def? It cant be cal mag, I add it to every batch of watering water. I swear by Cal-Mag, so whats my problem and what can I do? I think the PH may be a little low if someone cant point out the problem else ware.

I trimmed the infected leaves off, the rest of the plants seems fine but I did notice the rockwool has fungus of some sort on it. I covered it with tin foil to keep the light out.

Dont call me a moron just looking for constructive critisism, learning is key and Ive knocked down every plant prob ive come up against so far with yall help! thanks guys!

Educated responses please* no HS students who threw seeds in the dirt.

Ewww thats quite the algae bloom. Covering it will help i would think. And next time just cover it with Hydroton. Have you checked the plant problem section, lots of great links there as well.
