On my 2nd auto grow, made every rookie mistake first time, over watered, over fed and seriously challenged light that came with tent kit. Sewed 5 green Crack seeds and one white widow 17 days ago and they have reached between 16-20 cm in height and their leaves are now reaching the edges of their pots (10 gallon pots ). I want to try lst but as never done beforea bit nervous. Got hemp string jumbo paperclips and know how to attach but not sure if it's the right time and if plants are ok. Got them on 23/1 full spectrum phlizon 1500 led at @50 cm , is that about right? Any advice very gratefully received
