You have made a classic coco mistake. Coco is not soil or peat based (like pro-mix). So it requires a different approach to feeding. I think a 15gal pot is a bit big for this style, but we can make it work. You’re going to want to feed daily to runoff. And it’s going to take a lot of nutrient solution to get runoff from a 15 gal pot. You may need to go to twice a day, depending on how dry the coco gets later in flower. Ideally in coco you want smaller pots and auto fed multiple times a day. The lockout comes from nutrient salts dried on the coco fibers. When you water again, some of those salts are added to the solution, increasing the total ppm. This problem compounds over time if the coco is allowed to dry out after each feeding. That is why the coco should never dry out.
Thanks for the input! I flushed with two gallons of water a couple days back now, they are still pretty wet, should I continue feeding water until runoff? Maybe just use the Aptus additives, I am now in second day of flower.You have made a classic coco mistake. Coco is not soil or peat based (like pro-mix).

Sweet, I'm going to check that out. Thanks!Take about an hour or so and listen to Dr. MJ Coco's talks on the Growcast podcast. Not only is it fascinating but it's one of the few podcasts where I don't feel like I'm listening to two stoned people on the phone. Its a genuinely informative.
I'm a soil guy through and through and now considering coco. The advice given above matches that of what I hear from Dr Coco.
Good luck
Don’t worry about how wet the coco is. It’s only important that it doesn’t dry out. Remember, it’s not soil and has very little nutrition. So you will want to begin the daily feedings immediately. Even when at full saturation, coco still has enough oxygen for the roots. Overwatering is pretty hard to do in coco. But the plant needs those feedings to grow. Think of it like this, the plant eats what it wants and you’re just resetting the coco each time you feed. Whatever is not consumed is pushed out the bottom of the pot. Dr. Coco (cocoforcannabis.com) and I differ on a few aspects of growing but the way he explains fertigation in coco is right on.Thanks for the input!

To add I have good run off and when I go to water again the bottom 2/3 inches of the pot seems moist still. My plants are still in veg and I. Kept my gravity drip system installed and plan to run it again once the plants get bigger. I’m sure I will have to start watering more frequently as they grow. Buddy is doing similar setup and he’s watering every 30hrs. But is using straight canna coco.New guy here. However, I was doing almost the same setup. Emerald harvest 3 part, with added supplements. Emerald goddess, root wizard, honey chome and dark energy. I also started in 1 gallon and transplanted to 7 gallon smart pots. The canna coco was holding water and not drying out with my drip setup. And my plants locked up. Didn’t know if they would bounce back. I switched to a mix with perlite and my ph is 6.0 and EC at 1.4, growers choice ROI 680 LED, CO2. I started hand watering and BOOM. The girls took off. 72hrs between feedings. Temp 76-81 humidity 45-50. CO2 900-1500ppm. They seem super happy. I topped once at 2 weeks and they all have 5-6 stalks that all have a even canopy. Also doing 18/6 light. I think the medium helped a ton to get some air pockets and I was told to water every 30-40hrs and I was over watering. 72hrs seems to be the ticket for me. Hope this helps. I would think raising your CO2 levels and temp a little would help also. From what I have been told and read in the “bible” plants take in CO2 around 80 degrees the best. I could be wrong but it’s working great so far for me.

You can also flush with water and then feed after. You dont have to use nutrient water to get your runoff. You can just use plain water till you get your runoff then after it drains off hit it up with nutrient water.
Just to save some nutes. Ideally though a much smaller pot would be better. Indoor I've never gone bigger than 5 galon. A 5 galon can easily reach the 8ft ceiling.
”I usually use Cal Mag at least 1 time a month *at least*.“ Bro ,that was too crazy ,I'm a faithful Emerald Harvest supporter and user. I've been using it for a few years now. I don't mess with the 3 part stuff, so I cannot say much about that, other than I've heard of similar problems with the 3 part version, before. One thing you have to use that I didn't hear mention of, with Emerald Harvest nutes, is CAL MAG. Especially in hydro/coco. I usually use Cal Mag at least 1 time a month *at least*. And follow what these guys said.
Also, I've found Emerald Goddess works best as a foliar spray, not so much as a direct additive to your roots. It has a LOT of fertilizer salts to it, will raise your PPM by 100 with just a few drops it seems. EG is really strong tea I usually only go 1ml/gal in my hydroponics reservoir with that stuff. Use an emulsifier and mix EG about 4ml/gal with water, spray your leaves. After lights go out.
As for your 3 part stuff, perhaps give the 2 part Cali Pro a shot next time, it's much better, imho.
