I think you've got a SMALL problem with calcium deficiency ... easily solved by the addition of some CalMag! Those leaves probably won't get better looking but newer leaves should be just fine. Good luck!

Calcium / PH issues? Did I take the correct steps?
Am I on the right track to remedy my plant's issues? Seems like calcium deficiency to me. Soil test comes in at just under 6.5, my reservoir water going in is 7.3ph, in case its actually a lack of calcium and not the PH i've top dressed gypsum (and epsom salts).

Lockout during transition
Just a random question. I'm growing in a tent using coco and perlite. How do y'all keep your plants from getting nute lockout when they go from veg to flower? I seem to have this problem with every grow, no matter what I try with them. Thanks for any tips. ✌️ 💚 🌱

Deficiency or toxicity?
Hello i'm not sure what's going on, is this toxicity or deficiency? She loojs happy overall but new leaves have weird color, curled down tips, some of em are yellow and some are brow - burned.. maybe it's because she's transforming into bloom phase, PH 6.2 but runoff is PH 7.1.

The tips of the leaves turn yellow
The tips of the leaves turn yellow. I don't know how to identify the problem, is it the mycorrhizae that make them hungrier? Or do they just have too many nutrients?

Hello all, I am having some issues with my outdoor grow. It seems the leaves are beginning to turn yellow. It has not received nutrients I’d say in about a month. The main reason for asking is because I do not want to over correct by adding nutrients if that may not be an issue.

Auto flower deficiency
Hello I have a auto flower I grew in soil from last year. I believe this is a nitrogen deficiency but not sure. This plant is 37 days old and 1 week into flower. How can I fix this? Cal-mag? Worm poo? I'm not sure.

Yellowing to slight grey leaves
What's the cause of the older yellowing leaves with some grey and the slow spread to the newer growth? I'm between pH problems and or deficiency but not too sure.
