Hello I have been dosing PPS pro for 3 weeks now and love it. Plants are growing like mad. My question is can I dose at night after the lights go out or do I have to do it in the morning before the lights go on? I am currently dosing in the morning before leaving for work but I do forget once in a while. Just thought it would be easier to remember at night instead of at 5 in the morning. What are the problems with dosing at night?
