Nothing I do is helping. They are still filling out.

that's calcium deficiency symptoms. If you've been adding calcium it's lock out. If that's the case flush and add less micro nutrients. If not then add cal mag. Hope this helps ! 🚀

Test your run off dude. Test the soil PH. And if your not already make sure you have a PH pen for when you feed water. That's what I think

If you have tried to give it N + P and its not worked id suggest calcium!! see them brown spots on some of ur leaves only know cause its the only problem ive encountered and now they r back on. i flushed mine with calcium water at 220ppm but i had only just started flowering.

I should add that the plants all made it to the end and are being harvested. Slightly reduced yields but they’re worth seeing out to the end.

I’ve just been fighting the exact same problem with my current multi grow. I check and double checked everything and couldn’t find the cause. Flushed the plants - nothing - no improvement. One of my plants was germinated two weeks later than the others so I’m using that as a test subject. I flushed that with non ph balanced water straight from the tap ( around 7.6 ) and that plant is showing encouraging signs of improvement. Now, I can’t tell you why it’s improved and I’m not telling you to do the same thing but it helped me. Possible lockout is my theory but of what, I can’t say.

As with my info take it with a pinch of salt and confirm it elsewhere.Everyones an expert nut 30yrs gives me some knowledge.I certainly wouldn't feed it just water like others have said.This lady needs food.Its certainly lacking Calcium and Nitrogen but I guess its being locked out due to PH.

Must be a problem with the food.Could be due to PH.Could be too wet or lack of certain food like Calcium.Check your waters PH then flush then immediately after feed,make sure you add some Calcium.Make sure you let it dry out between feedsIf its a big pot of soil every 3 days is enough unless its a massive plant.Never feed daily in soil.Looks like its not taking in the food for one reason or another.

and be aware of OVERwater too cause those leaf's are bending down ⛔🚿

Look' like lake of some nutrient bro, cause the plant is scking all the nuts from the leaf to get those bud's bigger. If you have a chance to get some top max from Biobizz and some 1 component B'cuzz from Atami for next grow will balance very well your baby's. Let the leaf's burn and flush your plant 2 week's before harvest. Best of luck 👍🏻☘️

This looks like a late-stage magnesium deficiency or lockout. I would flush this lady soon and don't give her anything but ph'd balance water until she starts to look better, the leaves that are damaged will not get better so it wouldn't hurt to remove them. Hopefully, things get better for you growmie.
