Hey
@Cerebral Goo ! Thanks for the video link. I've watched a few from GreeneGene. I'm still waiting on the gypsum, typical stock vs shipping delays.
I did manage to remedy the situation. I had seen it before but it only hit half the plants and just a few leaves. This time I was ready to post if I saw it starting again
I've been running a modified version of Genes MKP formula. I did equal parts A B Epsom and the Jacks "Bloom" product. 2g of each per gallon. Since Gene was going with a P/K boost I essentially did the same. Seems to have worked . I've got maybe 5 spotted up leaves and a couple lightly discolored here and there but no further spread.
It's week 9 starting today and will be the last 2g A/B/Ep/Bloom. From week 10 I'm going to run the Jacks "Finish" and see how it turns out.
