I could use some more info. What you provided was kind of vague. Temps, medium, fertilizers. Everything really, will help guys diagnose your problem. I saw what looked like stippling which comes from spider mites. If you have them you'll find them under the leaves. They're very small. About the size of the period at the end of this sentence. There are sprays that help. Neem oil sprayed when the mites are babies helps. Axomax, Safer Soap all help but timing the spray to the mites life cycle is the most helpful info I can give you. Good luck and plz let me know if you need any more direction.
