Color of top leaves

Hey pal. This is a case of marco/micro nute balance been off. As I can see in your profile pics the problem leafs seem to be the sugar leafs/leafs coming directly from bud sites? And your fan leafs are of an okay color yes? Okay, so here is the simplest version I can explain and then you'll need to look it up to understand more, don't worry ill also give u the fix. If you want more detail DM me. Okay, so here goes. Autos have things like ruderails its what gives them the ability to grow within a 9-11 wk period and they control their own flip. With ruderails the more an auto has, and some info on autos has the amount of % of RR. Anyways these RR need micro nutes, (immobile nutes), as apposed to marco nutes stuff like NPK and 1 or 2 others that get draw from your bud sites and brough to new growth such as flowering bud sites. With micro nutes you'll see these leafs showing defs around the very sugar leafs, or top leafs as you call them the leafs around the bud sites yes? I haven't had a look at your nutes and what you are using but I'll look what thru has the best/most micro nutes to help with your problem. Now, them leafs won't get better, they'll stay like that but nor will they get worse and more importantly it'll but your bud sites back to growing cause atm they aren't doing much when focusing on drawing nutes/energy from your bud site to help the leafs. Its all very complicated. Really interesting stuff and when you get an understanding of it and how giving flower/PK boosts at the right time will transform your grows. Really key stuff to learn. Micro=immobile/marco mobile nutes also look up fungi/root stims. Helps nute uptake. Will pop onto ur diary now.
