Getting ready to flower so I switched from MH to HPS, I’ve been running the Solis tek 600w MH at the 400 “Boost” setting at 18” above the canopy and they’ve done great.
I switched to the Hortilux super HPS and ran it at a full 600 watts, and after about 5 hours the plants freaked out. I had the light raised 36” and added a fan low near the passive intake. My temps read 78° and 50% RH. But I just the light was just to much, fan leaves on the KK stood up almost straight and started to canoe, the AI fan leaf tips all curled under... back down to 400 boost....

I’d have started with Autos or, at least, feminized photosensitive strains - just to avoid one of the problems you’ve had. All my seeds go into media with zero (or close to it) nutrients. The seedling doesn’t need any nutrients at all for st least 2 weeks and providing them at that early stage can kill or stunt them. Also, you mentioned watering every day...cannabis likes a dry out period and doesn’t like constantly wet soil. So, watering thoroughly (to runoff) and then letting them be until the top 1.5”-2” are basically dry before watering again will really help. Overwatering is one of the biggest problems newer growers have and it can really encourage fungus gnats - a problem you definitely don’t want!
Hope this help. Happy growing!
Damping off is fugus/mold attacking seedlings when they are in an overly damp environment.
I’m in coco, watering multiple times a day brings in not only water/nutrients but also oxygen. Drying out coco causes salt build up and ppm spikes.
You can grow big plants in small pots with coco, I’m in 3 gallon smart pots and my next run I want to use 2 galllon.
Thanks for checking out my grow.
