Update - Lazy Ass Mo Fo
Lord forgive me, for I have been a lazyy bastard...
I started to see white spotts on a few plants. Coudnt put my finger on what it was. I've seen all sorts and know my water, when I neeed to add X, when to foliar feed X. I messaged the smart arse they call
@Bulls, asked if he been sneaking in at night and adding bleach again (yep, some people just hater yall). He said nope, asked what PH im feeding at... PH, what is this strange word I asked
I've not used a PH pen in some time, I've been used to my water, the amounts of PH down needed. Well, that's come back to bite me in the arse. I should have known as I let a few plants get Cal Def for a video I'm doing on the differences between LED and HPS, the cal def was a fecker to fix where normally its a 2-3 day thing.
Anyway, I got a new PH pen, and... I've been feeding at 5.4 and 5.3 in the 2 tanks. The water has definitely changed. I'll whack the PH up to 6.3 today, and flood them pots full to get the root zone PH back into range.
Full update coming tonight.
