Fan Leaves Dying 60-75% through flowering.

Hey all, not sure if this is something to worry about but I’m definitely worried. Nearly all my fan leaves are yellowing and dying off. Interesting nearly all leaves near the bud sites are a very health green, it’s just the large fan leaves or ones a little further from bud sites. However in some cases small leaves not directly near bud sites are also dying off
I had defoliating a few weeks prior due to heavy foliage and early signs of mildew, so this is now kind of compounding that decision.

I have read this can be expected as flowering gets closer but I’m in Toronto, ON and could potentially go another 4-6 weeks at most.

Attached pics of the most afflicted plant. I do not have a reliable ph tester. I have been giving them tiger bloom extra strength about once a week. Growing in sunshine mix 4 and ocean forest in the bottom halves of the 30 gallon grow bags.

perhaps go every other watering on the nutes as it suggests?

Looks nitrogen deficient to me. I use sunshine 4 and there’s not much in it for nutes, ocean forest is good but it only lasts so long. Tiger bloom doesn’t have much N in it either, I think anyway. Don’t pull off any more fans unless they’re real done, the plant is using the N in them and moving it to the growing tips.
Me, I’d hit them with a high N liquid fert along with the tiger bloom. Who makes Tiger bloom, Foxfarm? You’re in TO so you should have lots of access to hydro stores, maybe try a couple of ferts with something from their veg line.

They are just hungry, I'd give them some fish hydrolysate but anything with some N will do. Amino acids are just a great fast acting N fertilizer that makes for some dank buds.

I've got the same thing going on. I fed some grow big to up the N. We'll see what happens. I hope you have a good harvest.

Ok OK not nearly all of them are affected.
You can see it yellow from the bottom up.
The plant protects what it considers valuable, its flowers. Nutrients are being transported to the bud sites. From the fans.

To slow that, feed it. As mentioned, they are simply hungry.

Ok thanks all! Did as suggested and fed them the tiger bloom as well what I used for veg which was nitrogen heavy. Should have realized that was the issue really.
