Man, what a day yesterday...
I was doing a reservoir change and decided to do a FULL clean on all buckets and rez. Emptied till the last drop, wiped thoroughly with clean cloth and stupidly decided to add H2O2 on the new water to help sterilize pipes and chiller.
What a fucking dumb mistake, I was looking online for dosages and boys, oh boys, don't you ever trust broscience... Read somewhere it was safe to add up to 5ml/gal of 35% H2O2 and I went ahead and added 80ml of this shit on my system.
Almost immediately the plants started wilting, too bad I didn't take a pic, seriously, they looked like dead within a few minutes.
Luckily I didn't leave the room and was fortunate enough to realize what went wrong and dumped all the water before it was too late.
By the end of the day they seemed to have recovered.
Apart from this, flowers starting to show on this new 20/4 light regimen. Pretty late for allegedly autoflower strain...
Since they were stressed I decided not to bump the nutes straight away, so I've kept it at EC 1.2 for now, RO 0 + 100ppm Calmag + 500 nutes.
I'll let they get back to speed and then bump it a little more if they don't show burn.
I'm still struggling with CalMag, some leafs showing issues, I've been using Mag Sulphate and Cal Nitrate , Lab grade powders, I've got some CaliMagic coming and will use it instead soon.
