1 week into flowering haven't used any nutes yet they are in a mix of FFOF it's only the very bottom set of leaves affected. I have general organics nutes to use I'm just not sure what I should use right now. They are a month old

I'd add in some Cal/Mg. The necrosis of your leaves is what you should be watching. The stuff that's dead will stay dead. You just want it to stop from continuing on to other/new growth. You're leaves look heavy. How often are you watering? Pot size?

3 gallon pots i only water them when they are light. this picture was taken prior to watering after 3 days without water thats why they are slightly droopy
 
I had a similar situation and it turned out to be lack of light on the underside of the plant. how big is it? what kind of lights you got going? A little trimming and putting some lights at dirt level shining up into the center mass restored the lower end of the plant for me. Mine is really thick and bushy though so I'm not 100% on yours.

A full image of the plant might help. But if you have a spare light that you can stick on the side at the bottom it can't hurt and I would only use water for a bit, if it keeps spreading you can start flushing and checking ph.

It's not a bushy plant the lower leaves get plenty of light.
 
For sure not a lack of light on the underside...:wall: Not sure if I've ever heard of that. I'd go Cal/mag... lack of light will cause things to stretch and stunt growth. It for doesn't cause necrosis of leaf tissue...
 
Just add dolomite lime a tablespoon a gallon and it will help fox is suppossed to have it in there already but their soil is very inconsistant.
 
I would foliar feed cal mag and try to find some crushed dolomite lime and top dress a couple table spoons and water it in

Will they have this at hydro stores? And 3 tablespoons for a 3 gallon pot? Do I continue to add this or is it a one time thing?

Thanks for your help! I appreciate it. I wish they would make a iphone app for this site as I use grass city app but rollitup seems like a much better forum
 
The dolomitic lime is time released. It won't fix your calmag problem overnight but will gradually buffer your pH over time. I usually add it by mixing it into my soil before planting and I top dress a few weeks into flower.

Yes they'll have it at hydro shops. A huge 25 pound bag of agricultural dolo lime is like 20 dollars. And do foliar calmag to correct the problem in the short term.

Its like 10 bucks at lowes or home depot.
The foliar feed is to help it along while the lime starts to work. Lime for me anyway will last a auto grow
If you get the pulverized , crushed , or powdered lime it takes 1-2 weeks to start working. Don't get the pellet lime its time release
