How they looking guys.

I'd stop foliar spraying - especially in later bloom. Even if not this time, you will eventually cause bud rot and other growth on your plant that you won't like. if it was for a reason like a pest, just ignore me. Like MiG said, it's a tad dark. If you don't have those meters, just dial back on nutrients for a bit - once leaves lighten a bit, resume but maybe not as often as before. if you irrigate with water-only, make sure the pH is 6.5-7 for soil. 6-7 is likely fine too. pH strips that resolve down to .1 pH are worth the few bucks for 100 of them. Once you know your tap and tap+nutes, you don't have to pH unles you see a problem. whatever you do to adjust it will remain consistent. well-water would be a possible exception -- heavy rains could change your pH of the water table, i guess? any inconsistent source would need to be spot-checked for pH occasionally.

Looks a little bit dark, how high is the ph value and the ec value? Otherwise it looks great 😍🙏🏻
