I love it that you have tap water listed as your nutrient! Lol ๐ mine would or should say hose water.
I see just a couple yellowing leaves on the bottom and they appear to be dying off, so nitrogen deficiency, add more of it, either find a chicken and have it poop in your soil bed, or go get some nitrogen products. The top has one mega bleached spot, was that there before or after you were blastin her with 20 hours of light? Chop that leaf off and say au revoir mon ami! N'abandonnez jamais, continuer le combat mon ami! ๐
