help identifying issue during flower

After a very impressive outdoor veg, I am having a not so impressive flower so far.. mostly only small buds. most smaller/lower growth is having some serious discoloration (see pictures).

been battling spider mites, grasshoppers and powdery mildew all year.. been using neem oil and growsafe spray periodically

two different strains of plant (strains unknown). currently using calmag, tigerbloom, bigbloom, and beastie bloom (beastiebloom at half recommended dosage). feeding every 5 days. pH of well water is 6.5. I've been following the foxfarm feeding schedule (with the addition of calmag). growing in 5 gallon buckets and also straight into a raised bed. drainage is good. all plants having similar problems.

started showing signs about 3 weeks ago. i thought maybe a nutrient lockout, so I flushed them two weeks ago after using open sesame for a few waterings. they're certainly alive but the flower production is weak, especially after such an crazy veg (about 7-8 feet tall). at this time last year, the same strain was flowering 1000% better at this point, although the plants were not nearly as big. I have about 3 more weeks before it gets too cold here.

any advice would be greatly appreciated. thank you in advance

Can you tell by the looks? Its a new grow spot and been using neem frequently

Bump

Well. That last post help. It does appear to be either a deficiency or spot disease. But have you possibly sprayed late enough in the morning that the plants haven’t had a good decent amount of time to dry?
neem oil out in the sun will burn the shit out of the plant, especially the tender new growth and leaf tips.

possibly. But its been weeks since ive used neem. The first sign of flower (2.5 weeks ago) i stopped using neem. So still not sure whats going on with the new growth

it looks like neem phytotoxicity

Never using that crap again. I only used it at dusk. The plant salvageable?

Might seem a bit harsh. But I’d try trimming off the dead tips and defoliating the leaves that look bad. But them in a bag, don’t drop to the ground. Just give straight water and see how they do .

i make sure all trimmings or dead foliage is shipped off immediately. i think if i trim the dead/discolored off the plant i may be left with only the stems.
