Now after first time growing I would change many things in my grow. I would top the once soon as growth start after third node and only do low stress training , the first top was awesome on my four plants, the window for auto plants are not long enough i find for extra stressing. I Ph my water under 6.5 to 5.5 now just because when my water ph was at 6.5 my soil was testing at 7 which is not overly bad but, at water ph at 5.5 my soil is now in range of 6.5. Only reason I grow is for the art of growing only , it so much fun , the trouble shooting is fun. I fimed one of my plants and received 3 colas when topped i got two one plant i super cropped on one of my northern light auto’s in my eyes totally waste of time doing on an auto flower , I’d just use a support stick for strength , less stress and i would repot only once from solo, sometimes less is better I think. I would like to thank all for all posts and thank you sir mostly for responding...Thank you!!!
