Hi,
This is my first time growing in the veg stage, previous plants were given to me on switchover to 12/12, so wanted to get some opinions on how they are looking.

About 4-5 weeks old, in coco. Day temps 25⁰, 20⁰ night. Humidity 55-60%. 300w led set at 60%, 700mm height.

Water is rainwater with ppm of 100. Feeding (per 10 litres).. 10ml silicone, 6ml calmag (takes ppm to 200), Canna AB 20ml, Nitrozyme 10ml, Rhizotonic 20ml, Cannazyme 25ml, Fulvic acid 10ml. PPM of nutes is 950. pH at 6.0.

I was thinking leaves looking a ittle bright green and maybe need more nitrogen in the mix, and there's a little bit of inward leaf curl going on, lights too bright?

Thankyou!

Air circulation is possibly lacking a bit. The extractor fan doesn't get used much as it's been difficult to keep the humidity upmoast 50-55%. There are vents at bottom of tent to allow a bit of air in, but not much. There's a small usb fan inside circulating air a little in tent.

Forgot to emtion, gets sprayed once or twice a day with Fusion liquid co2.

Do you think an intake fan to blow more fresh air in would be beneficial?
