I would share my experiences with my first photoperiod grow where im using main line first time as well
TH Seeds - MK-ultra
Shareing 250w hps in ct system and a 90cmx90cmx180cm box.
She will start flowering in an autopot system.
I've got almost the full AN line but not planning to use everything now.
Advanced Nutrients sensi grow/bloom coco
AN woodoo juice
Potsil silica 0.1ml/l all time
She started her life in a grodan cube. I ordered some with bigger hole by accident and decided to fill up that hole with coco/perlitte and it worked well.
She progressed very well. Here on day 10 after broke the ground.
I was thinking why the grodan's top is green. Finally i think i got it. Im using Potsil which has deep green color i almost sure that cause that.
After 4 nodes came i cut back her. Cleared all the leaves and other nodes except the two fan wich connect straight to the two main nodes. Also she was transplanted in 6l pot before. I know those pebbles looks sily but i ran out from them
