Gayekstarted grow question 6y ago

During the flowering stage, I'm mixing a compote with N - 4.2, P - 3.2, K - 8, Mg - 0.96. The leaves at the tips are turning yellow; it might be a deficiency of some element, but I don't think it's an excess. I want to understand why the leaves are turning yellow.

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.

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own. I’m not sure if it’s a nutrient deficiency or blockout from ph or something else. I watered them only with water ph 6.5.
