my 1st expierement w/ a bubble bucket..... help

[POKINSMOT]

i took a plastic container that holds 1.5 gal of water and fashioned a net pot to suspend over it, then added 2 airstones and 2 pumps....

i started the bean in a peat plug til tap root showed, then put it into a rockwool slab (allprep done to it -ph was 6.4) put the rockwool into the bubbler and in 9 daze added nutes ..... 550ppm... ionic grow formula..
growth is completely out of controll on day 14..... but my leaves are cupping upward ..... theres no discoloration or wilting....yet ...
ive had them cup down in a soil grow but their looking like their searching for water ... should i foliar feed ??
WWYD?
