Cannabis sativa from the looks of it 🤭. Plant looks fine. It's in flowering and using up nutrients. Be sure to water properly and give enough potassium and phosphorus.

Yellow-ish leaves and brown spots
I ran into a small problem. The leaves of my RQS Critical are getting quite yellow and brown spots appear on some of the leaves. PH is kept between 6.1 and 6.5 while growing in organic soil. I feed according to the BioBizz schedule. Curled leaves have already been fixed.

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower
The odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

turned yellow, what's the problem?
The big burdock at the root started to turn yellow a couple of days ago, the tip is drying and bending. This is a deficiency of phosphorus and potassium on the 45th day from the nut (7th week) - or am I wrong? How to fix it?
