they are about day 16 in flower not sure what’s causing it they are in 7 gal pots super soil. Any thoughts on what’s causing it. I was thinking about top dressing at about Day 28. All I have been giving them is a mild compost tea every other water and started slf 100 at beginning of flower using dechlorinated water

My 2 cents would be overwatering,, your leafs look very droopy and stressed from moisture, Is it only the yellowing leafs that are having purple veins?

im thinking you need some magnesium

my first thoughts in the first pic was maybe over watering and needing food but after seeing the tops are so nice and dark green I really don't think you need to add anything more than Epsom

id dose them with 1tsp per gallon 1x and then reduce to 1/2 tsp per gallon every other

First off, you need to water! The plants are thirsty, that drooping is from under-watering, not over-watering! It's hard to say if something should be added, as without water, you will develop deficiencies..also, i see that all that yellowing down low is from leaves under the canopy, in the shade, and most of those leaves, i don't see any flowers attached to their nodes. The plant may be shedding them..however..you should note which nutrient the plant is taking first from those leaves it's shedding, and from the looks of it, and makes sense in mid-flower, it's potassium. So while your tops look good now, you will need to add potassium shortly so it doesn't affect the budding sites. For now, try watering every 3-4 days instead and see how that works, if you see any yellowing spreading, make sure to stay on the potassium (cannabis plants favorite food), and also keep magnesium levels up as you 'may' have an issue with that as well in short time.

good call
potassium def could also be a factor in leaf drop.....
I wouldn't have thought potassium first but its reasonable to me that its a possibility

Agree need water. The drooping stem is evidence. Drooping leaves? Overwater. Stems drooping? Need water. Potassium deficiency is the leaf issue.

They are in 7 gallon pots. I give them a gal each. Every 4 days now it seems
I'm with the others that see an underwatered plant.
The dry crispy dead leaves visible on the lower part of the plant are another sign.

Did you get runoff when you gave them 1 gallon??

1 gallon should be enough to get run off from a 7 gallon pot easily and every 4 days doesn't sound unreasonable, maybe you need every 3

but ive also seen leaf drop like that from other reasons, ive seen plants getting enough water drop like that from K def combgined with high temps

Maybe.
When looking at it as one quart or 4 cups per day for that size plant it doesn't sound like a lot to me.
I agree the dried leaves can be do to other reasons but it also happens to an underwatered plant.

I would also ask the OP how quickly he applies that water.
If he does it quickly he will get runoff from the water just passing through to the bottom and not have an evenly watered soil.
If he waters very slowly I would guess no runoff or at least it will be evenly watered if he does get runoff.

By comparison, in flower, at their thirstiest, i have to water usually on 3rd day, max 4th (growing in promix with average temps/humidity, and around 750 watts of hps and led lighting), and my 5 gallon bucket doesn't give runoff for 3.5L of water, neither do my 4 gallon buckets at 3L, so it's safe to see how a gallon going into a 7 gallon fabric pot, will not give runoff either.

I water in a circle bout half a gallon let it settle the. Do other half

Pots are plastic Cali pots same as sub oil uses
