hey man
looks like they bounced back nicely for ya! Personally i'd chill on the nutes, they seem to have just recovered and they look so nice.
bummer about those dour d's. Maybe since they're in such small pots you might be better off transplanting into some fresh soil instead of flushing? (just a thought. fresh soil does wonders sometimes).
What kind of soil are you using?
nice job getting them back in order man.. looks like it may have been the hut after all.
GL the rest of the way dude.
