Leaf yellowing.. week 6

Looking at your last week - I’d be worried you have some type of root issue developing. Unless they were just thirsty in the pic.. but you’ve got some bad looking wilting on all of them and some unusual symptoms on the leaves all showing up.. your in home stretch tho. I’d test run off for pH - maybe do a slurry test as well

You've got a long way to go with this grow yet and the leaves should definitely not be turning yellow. I note that you're still only giving them the Gaia Green All-Purpose and this is the problem - they're not wanting as much nitrogen now and definitely need more phosphorus and postassium so you should switch from the all-purpose to the power bloom! The plant is desperately asking for this switch - she needs a lot more of that P and K... That additional P and K targets bud growth as this is all the plant is doing now - if you get them on the bloom nutes, the buds will grow and become denser as well. If you make this change and, in a week, see more leaves becoming yellow and burning on the edges, then what's happened is that the excess nitrogen has locked out those important nutrients and you may need to flush your plant... It's certainly not ideal and most certainly not called for right now - but keep it in the back of your mind... Good luck!
