i am in need of some help, I have looked online and I can’t figure this out. I am using promix to grow. Everything has been fine up to week 1-2 of flower (in week 2) the pictures are a leaf from each plant (I have 2) . I have given them fox farm big bloom thinking this was a phosphorus def but it seems they have only gotten worse. I’m thinking possibly a mag def now? I am needing some help! Posting pictures now. It’s starting from bottom up

Have not done any calcium, the plants were good up until now but I am reading that I wouldn’t know for 4-6 weeks if they need it..

They need it and regularly. Calcium should be available from the start of the grow. It's immobile in the plant. Unlike nitrogen and some others.

I will add calcium today, do you think this is the problem I am seeing now?

By the way I suggest a foliar feeding of magnesium. Epsom salts. One tablespoon per gallon of water.
