I don't know if it is the cause of your problem, but your temperture is too low. 18C is 64F. You want to bring up your temp to 23 C. Can you move your envirolite a little closer to get the right temp? Also, I wouldn't fert most waterings...just everyother. How long since you repotted?


You may want to start some more, but I'd try to fix this problem before that way you don't end up making the same mistakes again, imho.
