Really stumped on this!
Gifted streign thriving is MLB,( MOTHER OF BERRY) A STREIGN DEVELOP HERE IN MAINE USA! Thank you so much for any input! Train wreck i purchase from you are feminize seeds! Is this ever a problem? Feminized seeds is new to me.
I would think it’s the Miracle-Gro. Not a great soil for growing cannabis typically as most of their products have time release fertilizer. You might want to transplant to new soil.
Did you check the PPM and pH ? that will give you a better idea of what your plants roots are living in.
Miracle Grow is a +/- for growing cannabis. More - than +. I have used it but had to flush it. Some people can make it work, I am not one of them. I prefer Black Gold with some coco in it to help it drain.
Also what distance is the LED from the plant and what LED is it (brand/watts)?
Nutrient burn all the way
I completely agree here, nutrient burn is what you’re experiencing. My first recommendation, throw away the miracle grow and buy some actual marijuana nutrients. It’ll help tremendously!
I agree, poor soil and too much fertilizer, nutrients.try to flush with water or even transplant maybe
