Im thinking about starting the flowering process in about a week or so, in terms of nutes any steps i should take? Sorry about all these questions, are there any good FAQs about general nutes for indoor grow? thanks
Hurricane2007 Reviewed by Hurricane2007 on . Chlorosis, Just Flushed now yellowing, Add Nutes?? Hey, so I just flushed my plant 5 days ago, and it looks like its recovered pretty well except I have two of the top leaves experiencing alot of yellowing. I looked at the online guide that showed pics w/ nutrient problems, and it kind of looked like zinc deficiency. Having flushed the plant recently, Im not sure what route to take with nutrients or not to treat my problem, was hoping for some advice/opinions. I took some pics but they wont upload right now, server probs, but the Rating: 5
