Ok so I got an Barney’s farm mimosa evo she’s 9 weeks from seed today……ro water as base(4PPM) cal mag up to 150-200ppm……. .75ml per gal of armor si (silica)…….4ml drip clean per gal…….and then just a and b sensi grow coco formula……it’s ph perfect but the silica I have on deck brings the ph to 8.7 so I always have to drop her down to 5.7-6.1…….5.9 gal pots of pure coco dtw………feeding them every day now at 750-800ppms 2gal each in a sitting to make sure their flushed every time I water……I also use 29%h2o2 in my Rez at 5ml per gal….one day after a 14hr shift I sanitized my Rez with 12% total str h2o2 spray and I compleat lay forgot to rinse it out befor feeding the mimosa evo……half way threw watering her I seen every top slumpe over beyond a 90vdeg angle………I flushed her immediately and within 24 hours she bounce back however she hasn’t been the same sense the incident happened don’t get me wrong she’s grown a lot since it happened but her leaves just don’t look right….could it be the chemical burns that did it? is she permanently damage from it or is there a deficiency that I’m not seeing? . i also have an indica dom ilgm Maui waui in their, both getting same feed……no issues what so ever………86f and 60-6r% rh consistently and my light is an optic slim 650s……hung at 3 feet exactly above canopy and turned waaaaaaaay down……co2 ppm is ambient as I don’t run it but the levels are elevated at 700-1200ppm as I have a lot of large snakes in that room

Update……I have switched to tap water (150ppm) and bump that up to 225-250 with cal mag……light is at 32 inches now and it’s running full power….. as an experiment I turned that light down to 25% power for a few days just to see if that plant was extra sensitive to light after being burned she did not get any better….. also I flipped her last night because I can already tell she’s going to take up a very large portion of my 5 x 5 and I can’t wait any longer or I’m going to run out of room, I defoliated her and I noticed it was only the tops that were affected none of the bottom leaves were abnormal looking just the tops so i’m starting to lean towards a non-mobile deficiency??? No fan was used during these pics……I have since added one….so wind burn is ruled out

I have also dropped the silica down from .75ml per liter, to .5ml per liter just in case it’s giving her lock out
 
That was like 3 weeks ago though that’s what worries me….. I also just checked and I am slightly out of vpd
