Canuk Auto AK / Auto Cheese

First time grower ! Using a 3ft x 3ft x 6ft tent with a Mars II 700 Watt Led, light soil mixture, 30% extra perlite for additional drainage. I had ordered a bunch of seeds and was given 4 Canuk Seeds Auto AK and Auto Cheese free with my order. I decided to start with these in case something went wrong. I thought i had started both Cheese but it turns out I started a Cheese and an AK auto. Not sure which is which so we'll figure that out as time goes Day 6 : They seem to have gotten even bigger from this morning. I've been unsure about watering since I've never planted directly into a 3 gallon before. They seem to be ok, I gave them about a liter each on day 5 around the center of the seedling. The pots still feel like they have some weight so I'll leave them and keep checking every morning. Day 7 : Not much visual change from yesterday. The big one seems to have gotten a tad bigger, while the little guy seems the same. Not seeing any droop so i guess watering has been good so far. Roots are busy burrowing down and laying the foundation for the next few weeks. Hopefully we'll see some vertical growth next week when i start the feed schedule Day 7 : Checked when I got home from work and the pots felt light. I had watered on day 5 but did not pay attention. Probably 500ml per plant. I just gave them 800ml each. No runoff but the pots feel much heavier. Hoping this will last to day 10, when I start the nutes
