@cnkice, you might be over watering as well. I use 5gal airpots with HP Pro Mix (soilless) and at this stage in growth I am watering about 2 quarts every 3-4 days.

I would back your light up to 36 inches or so. Usually when leaves get wrinkled like that its from heat or light stress. Also whats your watering schedule? It says 2.5gal per day.?

@Grower_Jefferis, Yup! That is how long it takes for the medium to dry, and then needs to be watered/fed again. Feel free to ask me anything! :)

@Basementganja, Hey awesome info! Just wondering if you can clarify somethings for me. Are you watering in between feedings? For example it says, "Days 21-28 - 1 gallon dosage of 750ppm, every ~4 days." Are you watering in the days between feedings or 4 days is how long your medium takes to dry out and needs to be water/fed again? Sorry, am newb trying to learn!
