4/22 Double checked where light intensity currently is. I’m getting about 640 PAR / 46 DLI at the highest part of the canopy, which is right where I wanna be. 4/25 The yellowing at the tips for FC seems to be getting worse. PH did drift up to 6.6 in the res but that’s probably not the cause. I’ve been assuming it’s light burn and after checking the PAR numbers again it was a touch high, around 47 DLI. I lowered the light intensity down to 610 PAR / 44 DLI. I suppose it could be nute burn, but I haven’t seen much in the way of clawing or dark green leaves. It is the first run with the autopot system though so maybe I’m going too hard considering there is zero runoff growing like this. Either way I decided to do a mini flush by dumping 2 gallons of RO water into the res, following my usual mix but skipping the calmag and nutrients. EC of that mix was only around 275 and after dumping it into the res with what water remained it became 410. I’ve been debating doing a flush like this anyways since I assume salts gotta be building up, and adding a weak EC water like this might help get them down.
