One week its high 80's the next your 103 its been unpredictable lately. Ill check on the feeding... But does it look like its a disease/plague? You guys dont how many people have told me this and am starting to question myself. They are now five foot plants, some have also died out of the no where, I personally think those were being overwatered... But these look different, I ve topped them to and they simply just come back to the same thing???
