dark, curled downwards and brown fan leavesWhy are the fan leaves dark, curled downwards and showing brown marks originating from the edges? Had an issue of dark and curled leaves for a week or 2, did think it was getting better (N2 deficiency) but now suddenly after not watering for a day the leaves are going brown.

Yellowing of leaves during flowerWhat is causing yellowing of the bottom/backside fan leaves during week 5 of flower? Should I worry about it spreading?
Increased bloom nutrients to 3ml/l recently but could have started when feeding 2ml/l. Or is this just leaves yellowing as a part of flowering?

Yellowing of top fan leavesWhat is causing yellowing of the top fan leaves?
Started to happen to a plant that I broke by accident during LST. However around the same time I upped to 2ml/l and moved the light a little closer. My ph has also been high (fine now). No idea which one could be the culprit
