1. Yeah it takes ages for it to dry, even with a fan inside.
2. temps are sitting around 20 to 25 on occasion.
3. Ok no more cal-mag from now on. I noticed a Mag deficiency and just added CalMag without thinking.
4. I am going to order a EC meter.
5. Ok will get this for my second grow.
6. How would I flush then?
7. Once a day watering sounds so much for me. It will be a hydroponic setup at that point! hahah. We are going into summer so maybe the heat can get fixed by this. I was always worried about temps higher than 26c.

No need to say sorry! This helps a lot. Will definitely implement this in my second coco grow.
If its taking forever to dry they are not feeding, lock out! Ditch the Ferts! Switch to Megacrop 2 Part, dollar to dollar its cheap and keeps up with the High dollar ferts, Ive been running it since 2018 I dont have issues in the garden, ever! Flushes are easy in coco, flush 2 gal thru plain pH water & calmag, then mix a final gal of "corrective nutrient solution" pour it thru. Youve just reset the Rhizome! @HerbalEdu has explained the cal/mag issue with that brand, is why I suggest the switch to MC, no compatibility issues! *Hanna Instruments HI98129/30 it has a replaceable ORP probe, Ive used mine for 10 years, Ive replaced the probe twice. Its accurate, holds Calibration for months, its a must have in Hydro. its not cheap but if your in the game for real buy the equipment you need.
Good Luck (if you are thinking/or switching MC you can DM me if any questions)

We dont have Gaia in my country. GH is available most places for a good price.
So far I am happy, but have no idea on how to use it.
same no gaia green where i live, that's why i was looking into greenhouse feeding organic line at first.

just follow the instructions from greenhouse feeding web site and you'll be fine
3. Ok no more cal-mag from now on. I noticed a Mag deficiency and just added CalMag without thinking.

yeah as long as you use greenhouse feeding powder mineral line of nutrients don't add liquid cal mag from another brand

4. I am going to order a EC meter.
definetly a must when growing in hydro

7. Once a day watering sounds so much for me. It will be a hydroponic setup at that point! hahah. We are going into summer so maybe the heat can get fixed by this. I was always worried about temps higher than 26c.

the thing with coco if you can treat it almost like soil or more like hydro regarding watering both are doable.

tho' if you treat it more like soil, you'r more at risk of ph and nutrient lockout.

here some tutorials about growing in coco you should have a look:

When it comes to the nutes I can’t really say much because I haven’t used them. When I’m using coco it is pretty much drain to waste hydro. If you add organic stuff like castings then you can treat it like soil but I haven’t had much luck with that. I just lower my nutes down the last week. .4-.5 ec. The watering is a lot. I use a 5 gallon bucket as a resevoir and got a 20 submersible pump to auto feed them. I keep the soil wet with that and hand water till runoff once a day. I check my runoff every day. Refill my 5 gallon every 2 days. Sounds like a lot but it’s 10 minutes once a day. I use to flush for 2 weeks but it has been way better since I stopped starving them.
I’m doing a side by side right now. One coco drain to waste and one super soil. There’s no comparison. The coco is more than doubling the soil. My pots go dry in hours.

for sure have a nute lock out.

Thank you! I dont have that brand either haha.... We do have Hanna Instruments HI98129/30 here. Honestly, I'm growing for the fun of it. Im not even smoking that much nowadays and I don't sell either... I used to have the BlueLabs truncheon or something forgot the name, this long pen..

Skimmed this thread a bit.. But the source of your issues seem to be watering practices.
Do not treat Coco coir the same way you would soil. Apply nothing you know about soil to Coco.

Coco should never dry out... Never allow any dry backs. If the Coco dries... Lockouts happen.

Each watering needs to be with nutrients and have calmag supplemented. Cal mag can either already be present in whatever nute base or from a standalone brand/source.

Each watering also needs 10-30% runoff.

Runnoff also needs to be dealt with because if it's reabsorbed... Lockout issues as well.
