Help what am I doing wrong

Here is the deal, I've killed two starts and down to one more start before I have to get more beans.

I'm startiing in 1 1/2 cube rockwool, soaking them in ph 5.5 for a couple of hours, I then shake off some water, put them in the grow tray with a dome, the are on a warmer, I'm getting them to sprout, all of them no problem, onced they sprout they don't grow and after a week they turn yellow and they just don't grow, I nuke them once they sprout at about 150-200ppm, I take them off the warmer, I keep the cubes pretty wet, I'm at a lost anyone willing to talk me throught and Ideal start.

Oh, when i water them the ph is around 5.5 and I use rain water.

Thanks.

no nutes til you see roots! that's the first thing; you're frying them.

and drowning them. cubes should be moist, not soaking. also, rw and cold temps don't mix and result in rotted roots. sounds like the nutes are your problem though.

Thanks for the input, I don't nute them until they are sprout, The tape root is out but not throught the cube yet. Can you give me a time idea when to first nute them (ballpark)4 day, 10day. But yea, I think I am overwatering them. Should I spray them in the dome or just keep the wool moist.

10-14 days from sprout. i'd lean toward the 14 day mark

toss the humidity dome, you don't need it with seedlings.

Your plants are drowning in the rock wool.

get some soil, light, and water.
