If your pH is at 4.5 your poisoning your plants. Hydro is 5.5 - 6.5, I like 6.0, soils are 6.0 - 7.0, I like 6.3 in my soil. It sounds like something is getting mixed wrong. What order are you adding your nutrients? pH perfect should go to 5.5, also what's the pH of your water before adding?

Correct, if your pH is 4.5, this is extremely acidic and not plant friendly at all! Somewhere closer to 6.5 is where you should be aiming for. Also remember, the more leaves you remove, the less energy your plant can make, thereby slowing growth and leading to (potentially) reduced yields too. Try only ever removing yellow leaves, for once they are yellow, they have served their purpose. Besides, if your plant did not need them, it would not have grown them in the first place! Cheers, Organoman.

Moist build up at bottom - overwatered I believe this seedling had too much moist. The soil was moisty when I filled the pot. Somehow the pot feels very heavy now and seems there is a build up at the bottom. I made some airpockets to the bottom. Should I wait or take it out and put it into a cup and dry the soil?
