I am new to hydroponics and am currently using the Kratky method in my basement. I am using a 5-6-27 fertilizer with a 15.5-0-0 CaN and Epson salts. my ratios are 2g fertilizer, 2g CaN and 1g epson.
My problem is growth is very slow and my lettuce leaves are not firm at all.

Would love some guidance from all you expertise.

Cheers
