Fkn killer grow!! ScrOG is top quality Perfect

There are 2 sets of leaves on the scrog showing some yellowing. Not sure what it is. I added some liquid silicon but i think the yellowing started a few days before the silicon was added. The plant which is yellowing is directly under the light but the light is 24" away from the canopy..
It looks similar to light bleaching but was wondering if anybody recognises it?
There is 3 weeks left so Could it be the start of yellowing due to flowering coming to an end?
Top Colas on my current TD have been yellowing the same for the past week or so. I also encountered the same with the biggest buds on my first three TD. Im pretty sure Seymour encountered some early yellowing 2-3 weeks before harvest also with his top colas. The other thing I had on my last td grow was that some of those leaves purpled and a few even went black, as long as its confined to a few buds I dont think you have anything to serious worry about.
defnitely loving that scrog action jake.
its a forest of bed -- makes me want to lay down.
