Hi, I’m about 6 weeks in so far. Things are going well, apart from the bottom fan leaves are going a lighter colour. I suspect they may not be getting the light they need. At this point is it a good idea to remove these so the plant doesn’t waste energy on this area?
Either way, they’re not hurting anything at the moment. Once you defoliate before flower, you can lean all those up. But, I always strip the bottoms of the first couple limbs and leaves, like a lollipop. The bottoms don’t get much light.
You're short on N.
As core NPK are mobile nutrients..
If your plant is lacking N for its new growth. It'll eat the the nearest source to the roots (in most cases) and this is just a case of needing more N pal.
Good Growing
It may be a nitrogen deficiency.
A cannabis nitrogen deficiency will cause the older, lower leaves on your plant to turn yellow, wilt away and eventually die. The plant typically appears pale or lime-colored.
