First dwc small scale need some help Pics

Thanks shaft n if u make a thread for odwc I will deffinitly subscribe and when I start in January I will hit u up probly on some specs for the whole thing and I'm for sure makin a grow journal next time just so I can keep track of my progress and it would help me out alot seeing as I suffer from shorterm memory loss alot lol

Ok sorry I haven't been online lately but here's an update

Don't know why I did it but somin tol me to cut the bottom 3 leafs off and leave the top three so I cut em off 3 days ago the day after I noticed some new upward growth in the stem and later that night all the newly formed leafs came out and since then it's just been a beast about an inch - half inch of growth a day roots are getting long really long and new ones form every day

I used distilled water and a 1/3rd dose of nutes last Tuesday when I switched water going to get a ppm/ec meter next weekend so just gonna leave her be for now and do the wavy water/nutes change Tuesday again then nex week I will admit accordingly

And does anyone have suggestions on what levels of ppm my water/nutes should be at using FF trio my plants 13 days old since cloned and she has 10 leafs

Also noticed the 6 lower leafs have curled tips downward shou I worry about this or is it common?
