Hey everyone beginner here only my 2nd grow, both in soilless peat/verm/perlite mix. I could really use some help I lost 3 seedlings already! I had 6 seedlings going and now they get to be an inch and won't grow. 3 are dead and the ones alive are green, but have not grown at all and the sprouts were planted 2 weeks ago. I ph my water and added dolomitic lime and azomite and bone meal in the mix. I just did a light feeding of earth juice to see if it would help and nothing. My last grow was a great success but the plants were very slow to take off and I thought it was due to having them in a colder environment. I have them under a 600w mh at 50%, and covered in cellophane to stop transpiration, any help would be greatly appreciated , thanks guys, good day and good smoke!
