Fellow growers,

All has been looking great in the garden until the last couple of days when I flipped to 12/12 ( Flowering Light Cycle) and all new growth is looking yellow and flimsy. ( See Picture)

Medium is Coco Coir/perlite and PH is 6.5 at watering.

Please let me know what you think as I am thinking it is lockout and how to fix it if possible.

Thanks in advance for your input :)

You get yellowing like that when growth is vigorous, think its due to sulphur and iron been slow at moving up to the new growth. Your making things worse by using soil PH in coco. You should slap it down to 5.8, they should improve slowly.
A dose of kelp wont hurt either.

Edit, I'm making the assumption that your nutrients have a proper dose of micros and macros

I am using Emerald Harvest from Advanced Nutrients. Just keept the A and B ( NPK) and added a bit of bloom booster for the first time since it is the first week of changing them into flowering. Next week I will go with Flowering Nutes in full effect.

Yes! Definitely going to bring PH down to 5.7-5.8. That will ensure that Zinc is not being locked out as well since I am in hydro medium, which is my biggest concern. Thanks bro.

Just looks like a burst of vigorous growth as the older parts of the leaves seem to be going green. Very common with fast growing plants and an indicator of health if anything.
