what is the problem?
The colors of the leaves make me think. I don't give a knock during these weeks of bloom time. Do you think this is a lack of calmag? or this is normal:)?

Why are leaves yellow?
As shown in the photos, I find yellow leaves of Northern Lights Auto. Until yesterday she has been growing in good health, but now her leaves look drooping and some of them yellow. Also she does not drink water. Why do you think it is? (deficit of nutrients?)

Upper leaves turning yellow - Day 28 of flowering - Cinderella Jack Auto
Only "half" of the plant is doing that. I don't think its a pH problem, the other plants are receiving the same source/quantity of water/nutes. My guess is the buds that are receiving more light are "maturing" quickly and the plant is sucking the leaves close to them. Thoughts?

Should I cut the dried leaves at the bottom?
Should I remove the dried leaf in the bottom? I was thinking that it might redirect unnecessary energy to the plant since the leaf might be too far gone to save. I was thinking of starting topping next week as well, when the fifth node start to show more.

Potential bud rot?
My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early? I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!

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.

On only one of my plants there is a brown spot which I have no idea where it can come from. I didn't give too much fertilizer and I regulate my ph between 6 and 6.5. Some idea?
