Critical cheese auto first grow

Hello again welcome back the critical cheese is looking decent, small but nice structure. Just been giving straight water around 800ml every 3 days or so. Have noticed bottom fan leaves turning yellow and some brown spots on some leaves. Not sure if this is a nitrogen issue or what. Brewing up a tea as I type this (2solo cups castings 2 tbsp power bloom and some molasses ) . Hoping it will help the lady’s . The third cheese auto I put outside because it was a week behind the other two and I figured it would be fun to see the difference between them. Also two clones I might sneak some pics of in a couple weeks ( mango , pink kush ). Until next week , beersy out.
