Whats wrong?

Help me. Been 27 days since planting the seed. under 600w with 15l air pot and canna coco pro. no nutes/feed yet. why is it so small and not growing? other grow journals suggest that something is wrong with my grow. any suggestions guys?

27 days and no nutes? She needs food bro. That might be why she's small

Coco is inert. Nothing usable at all. Seedling provide their own for about a week, not a month. Rule of thumb for coco: light nutrient solution on the third irrigation.

There are lots of things that it could be like over watering, ph problems, nute problem and so on. 27 days in coco with no nutes dose not sound to good of a start coco has no nutes in it, and your plant needs nutes to grow also with coco don't forget cal-mag additive you will need that.
I really think from what your saying you are starving your plants.

Also not sure if you did this but with coco you need to mix in about 30 to 50 % pearl light, and next time you start seeds start them in rapid rooters if you did not coco is not as good for seedlings.

Roots grow before plants increase in size,,,,same for transplants to a point. And everyone else is right, feed it!
