Getting Frosted

Week 4 was a bit sad. I was noticing discoloration on the leaves of all my plants. Thought maybe it was a nute burn, so I cut back the nutes to just recharge and water. Discoloration didnt stop so it must be something else. I decided to transplany my pepper plant which was very discolored. That is when I realized that they all needed to be transplanted. They were all root bound. I wasnt expecting suxh fast root growtg as i have never grown autoa. I should have transplanted last weekend or started them in the 3gal
