Yeah I think you’re right. They were outside since April. I have them in seven gal pit but once I switched to flower 18/6 they shot up like 2 feet!more important imo is whether you are going to outgrow your tent with 6ft plants just starting flower. honestly you may have waited too long
For the next batch I am going to do 3gal pots and a ScOG. This is when I tie them to the trellis to control growth correct?
