1st knock your light schedule down to either 20/4 or 18/6. Your plant needs a rest period. 2nd get the temps up from 20c during the day. 24-26c if you can. 3rd let your soil dry a little in between watering. 4th make sure your water is correct range for your medium.
@A123r, oh bro, i've been struggling since the beggining with pretty much everything, temp, humidity, bla bla bla, but yeah thankss! Your plant will glow up, just wait my man. gl
