I put these plants in a mix of FFOF AND FFHF about 3ish weeks ago. Everything was good until these spots. Also seems to be slight N def as well. Help

No schedule. I lift the pot. It's probably just time to transplant. They've been in those 1 gallon pots for around 3 weeks now

I would let them root out that pot. If they arnt drying out the pot in a day, theyre fine. If you up pot too quick and dont build a root system you will just need bigger pots that take up space and resources and when all is said and done, if you check out your root ball after harvest, you will find that alot of the soil isnt utilized. You will have a pad of circling roots on the bottom 1/3 if youre lucky and a mat on top. Meanwile the whole middle of the container will be empty.

pot size is a bummer when you cant keep up with watering is all, plants can be grown in one gallon bags just fine for years in veg.
ff is tricky but you look like you got a handle on it. your ph is off but you're right, a new bigger pot, with a mix of FF and promix will fix these swell. they look good man, nice job. is that neem making the fresh wax appearance?

Yeah the neem plus a setting agent puts that icky looking shine on them. But this deficiency is kicking my butt fast. I don't know if I should pot up in New soil or give them another week and feed them synthetically. I was trying to go entirely organic but it looks like they ate the food faster than I expected. Here's a pic of 24 hour progression. The N def is getting worse quick, and those spots are spreading0926171853.jpg

Not a deficiency! Chem hit it, ph is off. Plenty of food, they just cant get to it. When you water are you watering to run off?

I do water to run off. Only because these pots have holes I drilled in them. So some water runs out of the holes. So I make sure to water thoroughly. My Ph should be ok. I measure out to 6.4-6.7 every watering

Your waters ph and the ph of the soil are different things. Ffhf i have heard can be very acidic.

Ok. So I need some dolimite into the soil. I can do that. What would you suggest for my N issue? All I have at home is wiggle worm castings and 5-5-5 happy frog organic blend. I can dump a bunch of castings on the top, but maybe i would be better off than picking up some high n guano for a quick fix?

Or maybe I should just hit them with some chem. Not sure

I dont see an N deficiency. What you are seeing is your ph is out of whack, but not that bad. I dont know why you think you would have to correct with synthetic fert. Regardless of what it is, there is an organic option. N def would show in the lowest leaves first. N is mobile, the plant will take from the least useful to it and use it for new growth. Do you have a ph pen?

It's only low fan leaves and even lower tiny leaves being affected right now. I have a pen for my water.

container size~amount of dirt
divided by 4= the amount of water to add to your pot each time.

feel the weight of a new pot with dry dirt? add the right amount of water, dont water again until
the container is light again, or over water.

regardless of what you believe is going on....no additional fertilizer will improve your plant condition.
they will need fertilizer in flower, at onset, add your casting, avoid chems, dont buy the hype.
