What you have here is a heavy feeder. She's crying out for pk so she's taking what she can from the leaves. I honestly believe if you feed this one plant more pk she will bounce back! Also I strongly recommend some defoliation. It's not a calmag issue, it's not nitrogen and it's not from your water source. They looked healthy 2 weeks ago so must be because of the flowers, no? 👍🌱

I would have to say that you should use distilled water with pH set to 6.3-6.8 Calcium in the water plus your Cal/Mag might be too much for her. Just switching water might do miracles.

hello man, you are doing a very good work, yellow leaves are normal at this stage, maybe you could try to give more nutes, it depends on when you plan to flush your ladies, good luck with your harvest 💪🏻😜

I used cal/mag because in the beginning i accidently only used osmose water without any cal/mag...only wanted to give some after i switched to normal water to fight the deficiency but just kept on giving it as normal additive to every watering...it was biobizz alg-mix We have very high calcium water over here, so perhaps it's a Iron deficiency because with too much Cal there's a Iron lockout i read somewhere...
