answered grow question 6y ago
If it is late bloom then it is relatively normal for leaves to start yellowing. You could put in some cal mag if you wanted to but if you are nearing harvest or flushing then I wouldn't worry man., just leave it and continue as normal.

Once this plant switched to focusing on bud making she started to get sick. Once a week feeding of diluted 2-8-4 solution and Calmag with silica. Help. She gets thirsty very fast also.

Whats going on?
So.. 6th week into it. My leaves have various brown spots and yellowing spots in no particular spot. There is some browning on leaf edges. Also tips are up. I am thinking cal mag and to much heat. But not sure. I lifted light up and so far nothing. Also started adding cal mag .

Deficiencia o bloqueo de nutrientes
Como corregir esta deficiencia/bloqueo de nutrientes? Había tenido unos problemas de sobrefertilización que corregí con un lavado de raíz hace varios días. Y ahora las hojas de la planta están así. Alguien sabe que puede ser o como corregirlo? Gracias

More rusty spots
See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

45 days of flowering, is it a bad yellowing or it's normal for this phase? Always did 1ml/L of biogrow, I think I'll put 2ml/L till flush. It's nitrogen, right?

Is this definitely CalMag deficiency? Check diary for video.
Before I go to over the top with the CalMag in a stupid attempt to nurse my plants back to health I just want to know for certain what it is. The leaves are clawing, bronze spots everywhere but the smallest of the 3 doesn't seem to be suffering as much.. what is it?!

Cal Mag deficiency. Should I put it to flower?
Will the plant recover when it reaches this level of damage? This plant is at the end of vegetative growth. Is it okay to put to flower, or do I wait out? Many thanks.

Gave her enzimes last week, maybe they were too much or some nutrient lock out due to a somewhat excessive fertilization (too much vermicompost) Think I will go on with plain water to the end I think maybe the problem will sort out itself or wont degenerate too much. Any advice?
