They grow in Autopot under 400wattm in coco/perlite 50/50 mix. It all went well ontyl now. The pH of water was 6.1 though I strugle wih it every day adding acid to lower it to 5.8. They grow in a tent with a 23C temperature so no issues there. Previous fed was to concentrated and top of fan leafs have burned. I flused them with pH water and lowerd the dose. I flushed then agaih now and did not feed them yet because I dont know what is the prblem.
