Brown spots and yellowing
GrowingGrannieanswered grow question 3y ago
The problem again lies in your pH.... it's far too low for the essential nutrients to be absorbed by your plant. 6.2 is absolutely ideal but if you can get it between 6.0 and 6.5 you'll be fine.... I see you're giving her calmag - plant can't get at what you're giving her... get the pH up!
Good luck!

You actually have a magnesium deficiency. Often with this deficiency, magnesium is present, but the roots cannot absorb the magnesium properly due to an improper ph. Therefore it is very important to maintain the correct ph and make sure your ph does not get too low/acidic in order to avoid a magnesium deficiency. I would try bringing my ph up to between 6.0-6.5 that way the magnesium can be absorbed by the plant.

Organic peat controlI think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?

Did I do the right thing? Pls check my update on this week!Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

Pruning dilemmaI am noticing that some leaves are turning yellow at the very bottom of some plants, I think that there is not enough light coming through. So my question is (I did only LST and FIM --> on the main branch on every plant) should I start to prune some branches to empower top part?
