This middle plant rooted from clone I with 1 on left day 21 today. I received 5 cutting 4 rooted and these 2 are I thought all from the same mom. I use recirculating rockwool cubes buckets all plants fed the same from day 1. Ph 5.9 tds 1300 with general hydroponic expert recycling chart + armor si hydrogard and cal mag. Not sure what direction to go. Flush and just the necessities at half????

I don't know. I'm subbing because I'm curious and don't know how to sub without commenting.
But the first thing I would do is check for bugs and mildew because of the way the pictures look on my screen. Second thing would be to check the roots.
