Its nutrition man, its way too much, give her nutes then normal watering, normal watering again, and then nutes, don't keep giving her nutes every 2 days, sometimes less is more, this is one of those times.
Hope it helped, its DEFENITLY nute burn.
Follow instructions and you will do fine.
If you don't mind, pick my answer as it would help me deeply on the grower of the month contest.
Thanks.
Stay lit growmie.
