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).

If this was yours, how would you proceed?
Going into week 6. I just clipped the bad leaves that show in the picture and will be switching to the growing stage. I plan to do the 36 hours of darkness first. Already changed the water and it has the bloom solution instead of the grow solution. What would you do now?

Brown yellow leaves?
Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

My plants are 3 years old (counting from soaking the seeds) and they are growing really fast but the leaves are a little bit yellowish in the middle. Is this some kind of deficiency or maybe something else? I’m a newbie to this and need your help guys ;)

What’s happening with this plant? After watering all my plants 2 days ago, one of them has been quite droopy and developed these yellow areas with dark tips. Is it a watering issue / heat / deficiency? Thank you
