the leaves do look sunburnt

i live north of sac also and my water jumps overnight from 7ish to 7.6-7.8 but usually after i add my nutes its at about 6.5-6.7 with no need for ph adjustment

i think nutes should probly be in transitional phase now need much more p-k
i also use half strength nutes but i like the beastie bloom additive.
