Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

The leaves don't grow opposite, but point on the same side... there are also some yellowish spot on them. I put a photo of the others to compare.

Yellowing of leaves during flower What 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?

Yellow fan leaves New issue starting week 5 of bloom. The lowest big fan-leaves are getting yellow and that very quickly. She got a organic Biotabs PK Booster compost tea 3 days ago. It looks to me she wants more Nitrogen. Should I add molasses? If so how much? Or is it another issue. PH is ok.

2 Yellowing Fan Leaves I have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges. It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant. From research, it could be the bump in nutes or water issue. Any ideas?

Yellow lower leaves Hi! I went out for the weekend and when i came back most of my plants had yellow lower leaves. The weekend has been very very hot and im wondering if it was lack of watering or is it a lack of nitrogen? Some in one plant the leaves were dead.

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.
