germination help

my problem is that i just check my run off of a couple extra pieces of rockwool starter cubes i threw in there and it is 7.0. i pre soaked the cubes in 5.5 for a couple hrs then i soaked them in again with 5.8 with half strength super thrive. are my girls already done for and should i water them with plain water cause i didnt water them after i soaked them and put them in the tray and planted the seeds. please someone tell me ill be fine

I didn't think you were suppossed to use nutes on seedlings. Iv only ever grown in soil and germ'd in a tupperware box with moist paper towel. But i would think that half strength nutes would be to much maybe 1/4 would have been better. I would personally run water through them to get some of those nutes out.

super thrieve isnt a nute and myfriends use it to germ at one drop per gal but i did only half that (did one drop per gal then took half out and put clean distilled water)i really need to know if 6.9-7.0 is fine for germ in rockwool and if not what to do so i dont lose my girls. thanks
