Ok , firstly if this is in the wrong place im sorry, secondly if you are reading this thank you!
So i got this light from my wife about a 8 months ago i first used it as supplemental for flowering on my last grow and by the end of flowering my leaves were legit torched, but i didnt think much of it never got to bud sites so ohh well , onto the next grow and it severely started melting my plant right away, i grow in hydro so i thought its probably EC issue possibly nute burn (knowing that light burn is essentially nute burn) but the plant was burning up from tips at first then i started to notice black burn holes throughout leaves entirely…after cleaning out res and mixing up multiple batches of nutes to get PPM/PH all in range there was zero change…so thats when i swapped out the light and instantly plant recovered and is doing beautifully now. big question is why? …why does this $400 light suck so bad? below i will drop a few photos so you can see what im talkin about. again thank you for any help understanding the issue here. (I had light 27 inches above canopy, set to only 20%)
