Have any pest chemicals been used? If so, What and When? spider mites have been an issue, so tried a few things, osh's easy gone with synthetic pyrethrin(used many times before with no ill affects) and another natural remedy made by a hippy in s. cruz called a.n.b.o.m.(aint no bugs on me).
Are plant's infected with pest's the borg, aka the "santa cruz super mite"
so in order to keep the fuckers at bay, and often a few weeks before harvest i will take big leaves of, and as i have been doing this, noticing these turned down leaves obviously(like a claw), some of the lower growth is crispy, and the bigger leaves leaf stems will snap like a twig, although they are not dry, and some will snap a flower off with it... help
It looks like you have 2 things going on. The first is that you're burning them with too much N. That's the leaf curl and burnt tips. That's an easy fix: just back off on the micro a little.
The 2nd thing is that your pH is all over the place. The 2nd pic that you posted shows this the most clearly with the wavy leaves and lockout stripes. When I used to run hydro, I had my best results at around 5.7 in veg and around 5.9 in flower. With hard water, there is no reason why your pH should be fluctuating like that.
when plants are budding they suck nutes from the leaf to better the buds. A lil droop is alright when budding. Sometimes even in the perfect environment. There will be problems like that. even though i dont look at that kinda stuff as a problem. Just make sure they have the nutes they need. But other than that it looks like you still in a good position for exceptional buds. Keep on keep on.
