you have a ph issue so your nutrients are not doing what they should, to fix you need to flush until the run off ph is a 6. then wait until the plant drys out a bit and start using kelp in the feed mix. kelp is a good thing for plants to help with ph issues as well as other things, you will start using kelp and you will never look back again, good luck

Struggling with deficiencies (nutrient lockout?)Hello everyone, I need your help. I've been growing 2 Green Gelato Auto from RQS but I've had some deficiencies for a while now. It's my second grow and it's the first time that I adjust the pH. They are in soil and I'm feeding them with Biobizz liquid nutes at a pH between 6-7.

Fan leaves turning extremely yellow late flower Hello. Day 61 of flower, Green Crack 2.0 by Humboldt seed organization. Soil based. All of a sudden all the fan leaves are turning yellow. Trichomes are clear, no exceptions. Is it from finishing or did I mess up watering/nutes in the last couple of weeks? Thanks in advance.
