I'm curious what kind of blurple you're using? You're only 6 weeks in... I'm six weeks in and have buds that are far more dense... although there's been little new bud growth the last two weeks... they are bulging up and filling out like crazy. must be the MOAB. I burnt my plant also... too much nitrogen in flower will do that...
My light is a blurple cheap Chinese bestva3000 - I paid 250$ for it and absolutely believe you get what you pay for, at least when it comes to blurple lights. Although this is the only one I've owned, I'm glad I bought it. No heating problems, no vents none of that crap. I would urge you to up the quality of your light, even if you want to do blurple and learn more about playing with nutes. I have maybe 30 different products taking up the other half of my closet and a dosage poster I made to keep things orderly. Half doses or less are always best when confused/worried...
