@loop718 - How are you watering these anyways?

Just dumping in water into the pot, let it filter down?
how do you actually go about taking the water and applying it to the soil.

You could have compacted the soil, causing even longer waits for drying out. If you have been over watering, chances are it is.

No man i have a pump sprayer on low pressure and drizzle the water in. I didnt pack the pots tight with soil i kept the soil nice and loose when i transplanted.

Im only giving about 1/4 gallon to 3 gallons of soil every 4-5 days i dont think im overwatering if anything im waiting too long to feed again is the problem i think. The problem im having is the plants are eating so fast and my pots are too wet to feed them when they need more food.

this is telling me your grow area is a little cool.... should be 77-80 degrees ..... using LED temps should be 80-84 degrees ....

My room is 75-80f and 55% rh. Im using 8 row t5 for veg then swapping to led for flower. These are young plants also id say 3-4 weeks of veg they sprouted exactly 5 weeks ago today. I bumped the feed up this time lets see how it goes and how long until there ready for more food if pots are still wet again ill foliar them with some goodies and water in less next feed. Wish me luck and thanks for the help and concern everybody.

Having a hard time dialing these in lol. I fed yesterday 800ppm the last feed was 650 and the slurries were at 100ppm. most of the pbb are reaching for the light most of the nyc chem are drooping and have dark leaves and the tips starting to curl down. Is this N tox?

think this been covered , but which soil are you dealing with ? its not N tox.... leaves be dark green and a claw /taco

I agree with bubba, even 80 F is too cool, let room climb up to 85 F before exhaust fans suck it out. This will bump your humidity up too so you are in a better VPD range for uptake.....it will also allow more CO2 uptake.

#4 soil. The tips of the leaves are curling down and the leaves look darker green then before the feed. I may have jumped the gun on uping the ppms that much and maybe should of fed less amount more times like you said. I figured 1/4 gallon was a good amount i dont have any run off with that amount. Ill raise the temp of my room also.

I also hung my fan to make more floor room. Temps are 75-77F and RH is 65-75%. I think I'm in good VPD range from what I've seen and these girls can eat! Feeds have been around 1200ppm the last few times and they ain't fried yet lol

If you can get temps to 82 - 85 F then that's the VPD range for LED. Vapor pressure is based on leaf surface temps, not room temps.....LED doesn't have the UV & IR that traditional HID lights have so the leaf surface temps can be 10 degrees cooler then the air temp. You have the perfect VPD for HID lights, if you can bring up temps you will really get your leaves praying and hit peak performance from your COBs. The further into flower You gonna have to lower your humidity into the 45 - 55% range. Lookin good though!!

I made a couple changes on my fan controller before work this morning. I'll see how things look when I get home today. My temps should be in the 80-82F range, but unsure what my RH is gonna be doing, may need a small dehumidifier to keep it under 50% though. Peace out guys!

Few questions on vpd. I see if your temps are 77 and up it suggests 70%rh? How do you keep your room that humid? I have my exhaust fan running and it sucks out all the humidity my humidifier is pumping in. My space heater also dries the room out. I believe this is why my pots are so wet. My room is 77f and 50%rh the vpd scale has that in the red zone.

Thanks man, they responded super well to your suggestions.

I was talking with the local grow shop guy who runs NFTGs. Saying he might have to reduce the HH in bloom. The nugs are just fat rocks, grinders required lol.
Also he could likely kill someone with a NFTG nug with a slingshot lol. Ty again for all the help peeps.
