DWC Cash Crop Auto With cheap LED

Some info on me : this is basically like my 3rd grow, ever. the tent, the lights, the set up, all brand new, first time used and setup. my first time growing autoflowers. So here we are as seedlings (January 12th) in horrible grow conditions...inside a large bowl inside a 5 gallon bucket with a fish tank heater. low humidity, inside a cold tent, varying temps...awful conditions. seedlings stayed at this size for almost 8 days with no change until i knew something had to be done to make them happy. Lighting : viparspectra 600w LED with veg and bloom switched on rockwool cubes were not soaked or ph adjusted or soaked in nutrients before seeds were simply placed in them. I thought it would be a cool idea to try a 5/1 light cycle.
