The weather wasn't as cold this week and the plants are looking better. Nutes are at full strength now, next week I might top the plants. I plan to have a long veg for these girls for a few reasons so we're probably a third of the way into the veg stage.
Mate you need to switch on both the red and blue spectrum.
Plants react to blue light in a way that makes them think its very intense light they are under so they dont stretch as if you would have applied more red light.
If you wonder why your plants arent growing very tall, then thats why.
If you want them to stretch alot, then you should apply light from the 650 nm spectrum and up - Infrared and basic far red light is good for making plants stretch tall.
Happy growing 😎
