Edit: topped the Nuggz and applied some stakes for LST.
Some issues which I am still trying to fix.
1: my Nuggz is stacking its nodes very tightly, causing bad light penetration. Possible solution: raising the lights height
2: Both plants are somewhat stunted and show rusty spots on fan leaves. Possible solution: removing Power Roots so they do not compete with other nutrients. Raising A/B as I suspect this is caused by a deficiency. I also try to up the temperature so they recover more quickly as they are able to uptake more nutrients.
I have also ordered some liquid pH test drops to make sure that my Adwa ph pen is not lying to me.
