Dark green leaves in meringue
Is my girl telling me that the flowering fertilizer is too nitrogen loaded? I´m using top bloom from top crop, feeding at 1.4-1.6 Ec, and since last week I started to follow the feed-water-water schedule. The NPK of this fertilizer is 4-8-8. Should I adjust the input EC?

Deficiency?
Non riesco a capire se è una carenza o una bruciatura da luce, secondo voi? Cosa potrebbe essere ? Appare soprattutto sulle foglie a ventaglio....

I have a few brown spots and slight yellowing on a couple of my 3 finger leaves and even some on a 5 finger (#2). It seems to be getting worse every day. I have done a lot of research to find out what it could be but am very confused. Any ideas? Pictures from 2 different days.

Leaves brown down the length of half the leaf
I have some leaves that have gone a bit brown down one half, but along the length. See them in Day 40 pics (I have added a extra comment there). Does anyone know what that is? I was thinking maybe it is just the bits that have been sitting under other leaves, but I am not so sure

Leaves looking f’d?
What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worse

Brown spots and yellowing
What do you think this is? Nutrients deficiency or maybe soil ph. Happened overnight and the plants are a little dry but I just gave them water and nutrients. My ph tester has been broken so I’ve sorta been winging it with some ph strips.
