I'm not an expert at the whole plant problem thing. You need to wait for one of the mad scientist to chime in. However, I have gotten into overnuting, lockout and deficiency. I had that brown rust starting as spots then it was from the veins working inside out. One of the more experienced members on the site told me it was necrosis, lockout and my PH was all jacked up. Your plants don't look bad, but pics can be deceiving. If you are having issues, I think staying on the same nute schedule in the immediate term is going to futher aggravate, but again wait for one the pros to give you a more proper/technical diagnosis. But I would start thinking flush.
I have a problem with my plant. I am growing in FF ocean forest, FF nutes. It is a blue widow at 7 weeks veg. She is about 9 inches. I have three other ladies doin fine. I am using a 400 watt mh. Temps stay around 77-82. Humidity is 40 -60%. Not sure about ph, but all other three blue widows are fine. She started off with something that looks like rust. I just neem oiled her today. I looked online with no luck. All new growth is yellow. I was thinking of trying epsom salt to my nutes. By the way can you still give nutes with neem oil.
Any suggestions?
