40х40 sativa first grow

Hungry

It is normal for some of the bottom leaves to do this, yes, but it seems like various things are showing here as well. It seems like your girl is generally hungry for a few things. If you’re feeding properly, something else is causing her to not take up all she needs. I’d check out that ph and get her eating. You’re early into flower yet to be seeing this. Also, I wouldn’t cut off the leaves unless they are completely crunchy and dead. She will likely shed them herself when they’re no longer of use to her. Good luck

Looks like magnesium deficiency on some. Total yellow more lack of nitrogen, i see potash symptoms too. Hunger ? Bad ph for absorption ??? Big plants utilize/ canibalise bottom shaded leaves, thats normal, but here i think its something from above mentioned.
