I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

Leaves turning yellow with brown patches
I noticed the first real leaves on one of my plants turning yellow in FFOF. I transplanted them into bigger pots with ProMix M in hope that it would stop. Condition seems to continue worsening. I have started to notice the cotyledons on some of the plants turning yellow.

leaf tips #2
Hi, continuing the previous question. pH runoff was 6.1 So I decided not to flush and gave it CalMag. Since then yellow tips doesn't spread any further, but the fan leaves on lower branches become fully yellow and died. Does that mean problem is getting bigger and I should flush?

IMPORTANT excess/deficiency? What's happening? Flowering is in danger
What's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak

Hi every1👽😌Started week 7 of flowering today. How do they look to you? Is there anything I should pay special attention to? I think I may have overfed or overwatered them last time - I’m not sure which one - which could explain the leaf damage. What do you guys think overall?
