Long story short; I'm helping out with my parents five plant grow via phone/internet. Soil, organic ferts, 400w HPS. Strain is Wild Rose's Asshole (got this one pheno that is SOOOO nice but no means to take clones ). Anyway. I'm spending a week at their place and have had the opportunity to examine the plants in person. No spider mites or anything, BUT it looks like they've got a severe case of potassium deficiency. Anyone know what to do? I'm planning to pick up some kelp meal tomorrow and I have some seaweed concentrate I'll be making into a foiler spray. Is there anything else I can do? It looks to be a fairly advanced case - although the plants are still alive.
fuckfuckfuckfuckfuckfuckfuck I applied Safer's 3-in-1 organic insecticide/miticide/fungicide...misread the bottle (supposed to be applied in the dark wtf) and it looks like I just went and burned the plants - according to what I just read on the interwebs. No idea how a organic insecticidal soap with sulfur will magically burn the plant to death in the light but sweet jesus... ...I'm fucked aren't I?
