5 weeks from seed. Sunshine Mix #4 Water and very low Botanicare Pure Blend Grow (for 1 week; maybe 2 waterings) 8 seeds planted; this and 1 other are having the same issue; all others are thriving. pH unknown Over-watering? Could this plant just be more sensitive than the others or have poor genetics? Anyone have any ideas what the problem could be?
I allow the top layer of soil to dry out and become crusty before additional watering. In small cups like u have it shouldn't take long to dry out.
it looks like overwatering, but it could be a drainage issue in just those cups too... let them dry on the surface before you water again. doesn't look like a ph issue to me, but it cant hurt to check.... My sprouts usually take 3-10 days to dry enough to water(based on how much they drink, humidity, and drainage) so 2 in a week could be a bit much.
They don't need nutes in any amount at this stage and I believe you are both overwatering and too often watering. Think I'd cut longitudinal slits up the sides of the cup from top to bottom with a razor knife, about 10 of them, to increase evaporation. Dry them out well. Buy a spray bottle and don't water your plants with anything but the spray bottle until you transplant into a larger container, it will keep you from 'loving on them' too much
