The Super Lumens was probably too bright at that height. Turning the light down or raising the light should do the trick.I’m watering every other day with nutes and water in between I’ll b honest I’m not sure on how much I should b watering and stuff I’m goin more by how the pot feels in weight too pick up and when the top of the soil is dry and crusty at least an inch deep and then I’ll water again if needs be and I have watered more than a litre at a time but that problem I noticed I had accidentally knocked the lights too super lumen or something I believe it was 660w ffs so put back down too 400 and watered looked this morning before I go too work and all looks fine tbf I’ll post a pic later and hopefully everything seems ok....thank again
The amount you water pretty much depends on the size of your pot & how old & how much your plant drinks. The bigger it gets the more it drinks. I use at least 1 gal. every watering / feeding. But my plants are 4.5 weeks into flower so they drink a lot.
Back in early veg it was more like a 1/2 gal. every 2 - 3 days. Now it's 1 gal. per day. Water till 20% of what you put in comes out the bottom. This flushes out the salt build up in your soil & prevents a lock out from soil pH being off. Use the run off in your garden if you have one. I use mine on Oleanders & they love it.
