everything WAS going good.........

5th week of bagseed flowering. i've been using kool bloom and now i have what WERE healthy leaves turning yellow. I've been using the same feeding method since week one. i knew leaves turned yellow in the later weeks of flowering but the 5th week seems a little early. I waS going to put some 10-4-14 GH nute in a spray bottle and mist the plant but wasn't sure if that was a good idea. im thinking it needs some nitrogen........anyone have any suggestions? thanks.

I'm on my first grow so take it for what its worth...

From everything I have read, during the 5th-6th week your plants will deplete almost all N and will need a boost around there to finish off flowering, being you are in your 5th week that sounds about right.

I'm using Fox Farms nutes and in their feeding schedule they have you giving their Big Grow for a couple feedings to boost the N during the 5th and 6th week

Im no 100% sure but I dont think you should be spraying nutes on your plants and never do it when lights are on There are foliar feeding products out there for that. Can you post pictures?

Just a little issue I had, so may help. I grew my first plant a few months ago, no issues, went great, used the lucas formula and botanicare sweet. Added some humbolt gravity and had a issue, so stopped and it all was good again.
My second grow, I ran out of sweet, so in 12/12 bought some Kool Bloom and after a week I started getting issues, I think are caused from the Kool Bloom and I am thinking it is a magnesium toxicity. When I first noticed the issues, the next few days I added plain water and the problems stopped. So now I am not using Kool Bloom and will only use micro and grow flora Lucas method and a little flora Nectar and nothing else. I would say stop using the Kool bloom and see what happens. Even Flora Nectar has magnesium in it.

sounds totally normal. they should do that.
DO NOT ADD NITROGEN. you need to get rid of it by the harvest, not adding it.
