Youthmananswered grow question 2 years ago Hello! Yes let's say that the weeks meant by seedbanks are very variable, yours are still 2-3 weeks away :) it's normal that they take longer ! The symptoms are a nutrient burn anyway, so just give it water for a couple of times to clean the roots, and then half dose fertilizers (total max 4ml/l, 7.5 is too much !) And it should recover ! Then flush the last week :)
