ye nothing to worry about, it will prolly get 'worse' But i think its just a phase when you do it right..
The plant will get the N from the leaves which leaves this color as end result.
So if you feed more N during week 3-4-5 it won't be like this, but i don't recommend that at all..
You want the plant to start using the N leftovers, so you cure is less harsh when drying.
Then the chlorophyll doesn't need to break down so long which is in the green leaves and create a harshness to the smoke.
I have fed N before in week 5-6 and it creates unnecessary extra small leaves in the buds which are extra dark green and doesn't give a nice look after drying
That's my idea..
Btw is that Orange sherbert from Barney farm?
