I have 4 plants (different strains) going into 8th week of flowering and all have pretty decent buds and lots of (clear) trichomes. Since starting the flower phase I've had problems with yellow leaves except for one plant which is still pretty green. A couple plants also had curling tips but the yellowing started throughout the whole leaf at the same time on all plants and sometimes not from the bottom first.
For flowering I've used Maxi-Bloom by General Hydroponics which is 5-15-14 (and I used it last year) and has Calcium and Magnesium around 3.5-5% and other nutrients.
Why would all my leaves become yellow?
I flushed 2 of the plants over two weeks ago and the leaves have been dying but the buds continue to grow. I even added some Cal/Mag 2 weeks ago and I saw no improvement. Two plants are about 4-5 ft tall and the other is 7 ft tall (a Hawaiian strain).
I'm using 250W x 2 HPS lights at 12 hr/day for flowering and always get good ventilation. I was going to get a pH meter before I started this project but I ran into heat problems with my house so I had to spend money on that.
