have a look. its Acapulco gold from Barney farm. its about 3 weeks from seeds. water ph is about 6.6 . Using general hydroponics micro, gro, and bloom and calmag.
It is in rockwool. I used rapidstart on week one, the roots went crazy, shooting out all sides of rockwool. I then dropped the cubes into pots with dirt just to cover roots. this its only my second grow. first from seeds so I'm still a rookie here so be gentle.
you dont need to use the bloom this young. flush the soil, and when it looks better, start back with those at HALF the recommended dose. i used them too at half, and they worked great.
Over watered for sure but we don't know if they are over fertilized because he hasn't told us yet. If they haven't been fed much then don't flush, just let them dry out some first. You have good nutes just go easy while it is small.
Your first and foremost issue is too much water. Stop so much water, cut out the bloom nutes, and you plant might look decent in 2 weeks. What do I know though?
