So I got her flushed down to 6.6 from 7.8. Unfortunately I ran out of de-chlorinated water so the final flush will have to be tomorrow after my water been sitting out for 24hrs. So far it took well over 5-6 gallon of water to get her flushed down.
If anyone ever goes to use canna coco make sure you buy what you’re gonna use because I’m starting to think the coco started to get hot from sitting in my tote for over 2-3 months. Which is weird because I open it up every day give it a mix and then store it back. This is no longer gonna be an option for me. Or if it is I’ll be making sure to flush the coco before using it.
Honestly if I ran coco I’d use auto watering system with a reservoir. Prob a sip . Have to research.
I just flushed. I used recharge and this time I Ph’d after mixing. Seems to get my pH out of whack. Only thing I can think of. Usually I pH then add and run with it.
When I do feed the in is 6.2 and the out was 5.8-6.0. Until recently I checked with just the water going in and it was reading high 7’s. After flushing her out now she’s reading 6.6 but I have to wait until tomorrow this way there’s no chlorine in it to finish flushing her out.
Always feed every time no exceptions when your in coco. Soil can hold more nutrient ions than coco. With coco the food is in the water not the medium. If you give plain water your taking away the plants food supply. There really isn’t much storage capacity in coco like there is in soil.
Happy thanksgiving everybody, thankful for your guys help throughout my growing! Have a great day with the family everyone !
Little update my girlfriend recalibrated the ph pen and she messed up doing it so to put it short my medium was never affected. The ph pen was. Recalibrated the pen myself and took the reading and the medium ph is at 6.1 finishing out this month with just water and then switching to week 5 veg nutes on the 1st. Feeding through a foliage spray for the time being
Thanks growmie ! She’s gonna be a monster by the time I’m done. With it being topped the first time it gave me 2 main colas. Now that they got topped again and I topped the lower branches I should be looking at 10 main colas now . We might just get a little risky and top one more time after this but time will tell with that because I only have a 2.3x2.3x5.3 tent
It was starting to get hectic in there with all the garden spikes and tie downs. Switched over to the netting for the time being. Once she starts to get a little bit bigger I’ll go ahead and start fishing them through and get it all opened up in there. Limited in what I can do with the net for now. I say within 3-4 days when she gets a little bit bigger she’ll fit nicely in there.
So I’ve noticed if I feed foop 2x a day for 4 days that by the 3rd day my ph out is rising to 6.4 - 6.5. Which I don’t find it to be too concerning because the plant is not showing symptoms, but by the time I’m ready to switch to the following week I’ve found myself having to flush her out and get the out reading back to 5.8 - 6.2 does that seem to be a normal thing to have to do going forward ?
You probably need to adjust your feed/water routine. What is your coco/perlite ratio and pot size. What are your EC and PH in and out over time for the last 4-5 days? If you consistently have drift there is reason for it. The numbers will tell you something is wrong before the plant does. Sometimes it’s just lost efficiency, but usually it will turn into a problem given enough time.
Ph in is 6.2 and 6.2 for the first 4 days. After 4 days the in is 6.2 and the out is 6.4 - 6.6
Not exactly sure of the EC I have to get a new meter. But I know when I ran into this problem not long ago it was in need of a flush.
I’m gonna say around 1,200 it’s getting full amount now being in week 7 of veg.
%65-70 coco / %30-40 perlite 5 gallon fabric pot. If I feed at 7am she’s dry by 12-1 pm. The humidity is extremely low because that’s what she likes so she dries up fairly quick. That’s why I was doing a feed 2x a day and then water the following day of 2x. But you said to just feed her with no exceptions so I switched it to feed for 4 days 2x a day. And then water 3 days 2x a day.
So +/- .5 PH is normal drift. With coco the EC meter is very important since coco has relatively low buffering capacity. Unlike soil the EC and PH of the medium is pretty close to what goes in. For this reason water only will wash out most of the food and cause EC and PH. If coco is getting dry and your getting good saturation and runoff then you probably need to add a water event. Soil holds water far better than coco so if the top gets a little dry the center is probably still moist, but with coco if the top is dry the rest is probably dry as well. As the plant uses water left over nutrient ions combine to form salts. Those can also cause excessive PH and EC drift. Flushing is a good way to fix your numbers when things go wrong, but ideally they should just stay relatively stable and never need to be flushed. That is when you get the best growth.
I also have noticed when I lift it up off the base after it was done dripping and dried up a little bit I see a white deposit left behind as well ?? Could be a salt build up problem again with the foop ? Thinking about switching nutrients following grow
A little bit of salt buildup on the pot is pretty normal for coco in fabric pots. Its just a product of the fabric soaking up the nute solution and drying. It’s just on the outside of the pot. You can spray it with white vinegar and scrub it off right before you water, but honestly I just wash my bags between runs and its fine. It will probably happen no matter what nutes you use.
