xcrispi Reviewed by xcrispi on . yellowing tips of leaves?? help hello....I have a flood and drain cabinet with 5 feminized plants. I am in the 6th week of veg and everything was going great. Looked at the plants this morning and three of the plants had 1-2 yellowing tips on them. It was time to do a nutrient change (using GH 3 part system), but I checked the PH before and it was at 7.0-7.2. Would this be the reason for the yellowing tips or is it something else I should be looking at? I wanted to put the plants into flower stage (12/12) this weekend, Rating: 5
