Just starting out and have some questions. First off I have a 10x6.5 tent with 8” fan hooked to a carbon filter. Temp has stayed around 73-83 through the whole grow with humidity 50-80 of course 80 around seedling stage. I’m using a coco and perlite grow with 5 gal cloth pots.i have exhale co2 in the tent. Been watering daily with a ph around 6.5 and feeding every other day. I’ve done quite a bit of homework but my plants stems are looking a bit thin and doesn’t seem to be growing at the rate of other growers. Tomorrow will be week 3. I’m growing train wreck and nyc diesel. The stems don’t seem to be much bigger than at seedling stage, what can I do to correct this this grow or next?
