Northern Light [First grow]

First time growing, really excited :) Growing in a small setup with just 60 cm up to the light, so this will be interesting. Took 3 days to germinate, and waited too long to turn on the light, so it stretched a lot. I let it stay 3 more days in the Jiffy pellet until roots started showing at the bottom of the pellet. Then I transplanted it into a 3-liter fabric pot with a 70% coco and 30% perlite mix. I also started using GHE FloraSeries nutes aiming for around 250ppm. Also, I have my light at around 250 PPFD.

Not much to say. Started to add calmag, and I upped the nutes to 600 ppm. I turned the light up to almost 400 PPFD.

Decided that I want to try main-lining with this grow. I did the first topping this week. Topped the plant to the third node. Kind of painful 😥😋
