First time growing I don’t know northern lights plants turn it out growing great huge leaves and good stems top leaves started growing then and long canoeing and claw
Welcome. Photos and a clearer description of your problem my get more responses.
Fill out a growers form so we know what’s going on. Clawing and canoeing are clear signs of N burn. What nutrients are you’re using? Unfortunately with autos if you stress them too much early on they can flower prematurely so def want to get it under control ASAP. From the sounds of it I would guess you’re using a slow release fertilizer - Miracle grow is like this and is just too strong for cannabis. The problem is as you water (flush) you actually release more nutrients further exasperating the issue. Let us know what’s going on and we’ll do our best to help out. Very curious I just popped one of these as well good luck m8
