this is my first time growing so go easy on me lol ive just recently taken my cuttings from out of the tank as the roots looked nice and strong for transplant. they was under a florescent light, which they was doing alright. a few days after the transplant i got them under a 400w hps which is probably about 4/5 feet above the plants. i have them on a 18/6 light cycle, also have a fan constanly blowing on the plants for vent. ive just been watering the plants as the soil should have enough nutes in for now. i dont know the PH as of yet. my problem is they look like they're curling on the ends slightly and also slightly yellow, is this light burn? growth seems slow too. if there's any advice or help someone can give it would be appriciated greatly. sorry about the pics, im not the best photographer aswell as grower lol
