Pure Kush - First Indoor Grow

I would transplant them, it's amazing what transplanting into fresh medium can do. If you transplant, I would consider going to only soil or only coco, instead of a mix. If you do soil, look at the NPK of it. Some could last only a couple weeks and others 4+ weeks. If you go coco, feeding will need started immediately. Watering practices are very important during this stage, be careful not to over water.
