End of week 4 update
Plants are growing quick. All looking very healthy and happy. Feed only one time this week with a 680ppm. Did a bit of defoliation and some lst to help the light reach down inside the plant more. Cranked the light up a bit and moved it away from plants. Light burned a couple tips but it will all be good.
LPT: don't get high and man handle you plants or you'll end up snapping off the main stem like i did. So now I'm trying a topped autoflower. New territory. We will see how it goes.
