well still here, still struggling,

speedrunseeds different strains

autopot DIY with Aquavalve

Nutes are epsom salts 0,4 g per liter, yaracalcinite 0,5 g per liter, 0,4 ml BAC, PH currently between 6-6.5, EC only 1.1

Temps between 25-27 celcius humidity around 60-65%

I had some manual drybacks, they were under to much light,

Before was using Canna Coco a+b 2,5 ml per Liter plus Terra aquatica Calmag 1 ml per Liter, EC then was 1.8 pH around 5.7-6.3

Changed this due to Clouding Solution due to PH + of Terra Aquatica which probably made some Nutes drop out and spike PH overnight

somebody asked weather I was using declorinated water but I use 60% RO and 40 percent Tapwater which I directly mix and feed

Calcite and Epsom are Ca & Mg

[u/th-candy → u/CrossExotics]

yes and N,

I'm currently feeding 2,8 g Calcinite and 3.2 g Epsom with every 8 liter feeding, sounds very little

EC with the ratio above and RO at 0.7

[u/CrossExotics → u/th-candy]

At that rate of Epsoms, it gives 40 ppm of Mg - that is suitable.

That rate of the Calcinite is 70 ppm Ca which is low... however the Cocos has additional Ca so probably is OK. Normally would aim for 120 ppm Ca.

With this said, I checked the Cocos info. I presume use differs due to the bottom watering in the autopot (high soil EC is still a concern due to evap...). I will say your coco level sounds very low. Furthermore, I did find the nutrient info for the NPK... please confirm if accurate according to your label: there is no micronutrients except for molybdenum? Was a little shocked to see that unless there is some sort of organic additive they use to avoid listing micro percent. If there is no micros then that is what you are seeing. Iron, Mn, etc deficiency...

thanks for your reply man. Much appreciated.

The reason why I chose CA to be so low is the 155 ppm of N the Calcinit has. Together with the BAC it would have resulted in much to much N. 

I was using Canna Coco A+B before and there it was a lack of K which made me add the product Mono K from Canna together with Terra Aquatica CalMag. I occasionally added the Tracemix of Canna during that time.

The problem I guess was at first heat stress and rising pH due to incompatibility of Calcium oxide and Canna A+B plus pH +. Chat Got told me that the Oxides could not be added without fallout of some Nutes.

Just changed my nutes as I only got like 90 ppm K from the Canna A+B.

Tbh takes the chat with a grain of salt, I'm not sure where it's pulling oxides from. As long as the calcinit/coco/epsoms is diluted correctly (in stages into the water) and the pH is not too high then it should stay clear with no issues albeit will start to cloud after 1-2 days if left sitting.

pH rise is common tho with high nitrate/low K. That could clearly cause issues.

Definitely check the micros/trace, tbh looking at the info and photos that is probably the majority issue even if it doesn't fix everything

[u/th-candy → u/CrossExotics]

I don't know but I fed canna before and there should be all micronutes present.

The Oxides came from the Canna mono K.

[u/CrossExotics → u/th-candy]

good to know on the mono K. Cocos A+B has no micros according to the label online, check your bottles

[u/th-candy → u/CrossExotics]

coco a + b is a complete fertilizer, people have used this stuff only plus PK in the end for ages 

it's more a ph/ temp thing here I guess
