Powering through a revege... Give it a sec.
If that damage isn't all carryover, your ratio/concentration of fertilizer+soil nutirents (if applicable) isn't a healthhy mix and needs adjustment too. Smorgasborg of problems, but depends on when it occured.
If growth slows, dial back fertilization, too. Matter of balance/harmony. more inputs with slow growth leads to toxicity.
Growth may seem slow, but with a shit load of extra branching, it may just be spread out, so consider that possibility too. Consider thinning out some areas of the plant too. "Monster" cropping isn't really a benefit.. it's a problem that leads to congestion in most situations...
You still have funky leaves that don't look right, so it's not even 100% back into vegetative phase, yet. When new growth looks normal, i bet it looks healthier, too.
