We have mixed 1.5ml of grow , 1.5ml of micro and 1ml and bloom to the gallon , and using 1ml of cal mag !5.8-6.2 will be good for ph, I'd let them grow a little more before you top. Ok I see you're using AN nutes so don't worry too much about ph. Autos you can top around 14-21 days photos I usually top at 4-5 nodes.
Hope PH will be a problem if so I am not sure how to bring it down a little ?
So you would recommend I do top it ?
