Please answer asap

I planted 10 feminized seed in rockwool.....everything seemed to be going good until i transplanted them into 2 gallon buckets full of loose rockwool.....the leaves seem to be curling in arond the edges....i have everything set up in an ebb and flow under a 1000 MH but im not sure how much im supposed to water since rockwool usually retains allot of water....please and thank you far any help you can give

I assume you treated the rock wool pH before you used it. Sounds over watered. I would stop watering for 24 hours and look again.

My opinion is you shouldn't use only rockwool in an ebb and flow. If you must use rockwool use only the small cubes and set them on a bed of something that drains like hydroton. The when you water, fill up to the bottom of the rockwool cube, just touch it then drain immediately. do this twice a day.

Ight imma try that
