Very likely a cal/mag issue but just to rule out worse possibilities check for critters (Fungus Gnats and/or Spider Mites)Im about three weeks to a month from harvest. Water leaves and sugar leaves are being effected on the top of the plant mainly around the colas. What do you think and what should I do? Im using Advanced 3 part grow/micro/bloom with bud candy bud factor and overdrive(just started this one, but it started happening before) My other two plants on the same regiment are fine. wtf!!!
I don't have a tds meter, but this nutrient trio is "ph perfect" and I haven't been checking the ph in a while, but the first few weeks I did and it was in the 6.0-6.6 range, but the only thing that has changed with the nutrients is I am using a final phase bloom booster, overdrive, instead of what I was using at the beginning of flowering, big bud. Anyways, my other two plants look awesome still. I did a closer inspection of the plant with the issue and noticed a couple amber trichs, so I'm thinking it's going to be finished sooner than I thought, could this be the reason for the upper leaves changing?
