Robertsanswered grow question 3 months ago You likely need more perlite in the substrate, if it is coco it would be a ph issue. In this case i believe it is too wet and too much or not enough feed. Something seems not right there. The first 7 days the roots need just water and air. Then if in a soil it may be 2 to 4 weeks before you need to really get into feeding. Coco you start at 7 days, and maintain good ph run off from start.
