My first grow ever.
as my tent is only 50x50x120 i will try LST and if i get there use a screen.
Germinated them in potting soil, will move them in a 11l textile pot with Sonnenerde Schwarzerde.
First day was under a shitty amzn lamp before TS 600 was delivered.
I think you got more than one thing going on with this plant. Definitely a rootzone problem, either overwatering or pH. Address this first before playing with your nutes, they may be linked.
