I think its the coco medium. I tried it once and they all got an ok start but after a week they all collapsed and withered.
Cant treat coco like its soil and vice versa. It needs a specific kind of watering and i believe some extra magnesium.
Think its best to do some research on how to use coco properly. And when you do let me know :D
GL!
Yes I m agree, nutrient burn. Have you used pre-fert soil? It isn t good from seedling! But no worry, you have to do nothing, let your plant grow and all comes good. DON'T GIVE NUTS AT THIS TIME. Wait plant arrives at 4 nodes to start it! Good luck!
Way too much nutrition. Plant Is cooking in soil. Baby plant, baby diet. At day 10 I apply 3 drops of each base nutrition at day 12 I double it. Day 14 it is .25ml to l. Etc... if all is going good.
