First off…. Thx for the heads up I’ll give it a try next run thx bud…I got One of them already, I’m ocd lol I check influx and outflux run off ph and ppm every day …. But I gotta be honest man……I tried Dina grow….. hang on let me look at my bottle……it’s their GROW 7-9-5 and I had start to finish non stop cal mag issues…. I’m coco dtw though…. I tried useing my tap water which are. That time was in summer so it was sitting at around145-155ppm from tap…then I added their GROW until it was within 400-425 ppm and slowly bumped up to 600…… from day 14 from seed to just before week 5 from seed, I had non stop def which in turn caused other def….. ph was z..5.8 -5.9 for first 2 weeks….. from 5.9 down to 5.8 seemed to Slow down the advancement of that nutrient deficiency which I believe was CalmaG but I’m new with this so I could be wrong it kind of looks like magnesium and zinc deficiency combined into one so I could be wrong………..after week 2…. It really started setting in……… switched to flora nova and kept the same exact ph and ppm….. Within 3 days they were roaring at my every time ok opened my tent lol………Down side………….. this fucking flora nova…………. I lost power for 2.5 hrs and my water chiller got a touch to warm……. Few days after that….. sure as shit…… even with 5Ml per gal 29% h2o2 I saw floaters in my rez……… flushed With h2o2 that was strong enough to oxidize skin on contact an etch concrete….. ran a resurcation cycle for 1 hr then flushed with 150 gal of tap…….Few weeks later (yesterday) boom……it’s fucking back with vengeance…. I suspect becuSe I killed good and bad microbes…. And bad ones are always going to be more resilient……… and they just took the fuck off……. Now today….. was cleaning it with h2o2,c2h4o3 and ch3cooh……. Got finished and hooked tap hose up to the in Port and turned it on to flush her out…….. don’t I hear a fucking pop…… cracked my water chamber containing the titanium coils….started pissing out the bottom………. Thank god for ppe………… rinced her off good and took her apart and threw a heavy bead of flex seal caulk and blocked the one port and sucked in the other one and held the suction a little bit to help walk that sealant up inside the crack…….. worked like a fucking charm……..I’ll know soon if she can handle a slightly stronger pump………….so if you guys ever have that happen…….your welcome……you see I’m not perfect……I fuck up too…...
