The yellow spots that were seen last week have multiplied and started to appear on newer leaves. I should mention my tap water E.C is 0.8 so quite high. I still however added calmag this at it seems to look like a calcium deficiency. Are they to young for one though? Thank you

Hi there fellow Grower, this is calcium deficiency plane and simple. This deficiency can be caused by excess or miss of something. I had that with my NL if you have the curiosity is possible to see one with severe simptomes in my diaryes. Follow a few ideas: 0-always flush the coco before use, specially the brick ones and cheap unbranded. That removes the salts that might be there... You can still flush in any case just be carefull not to overwater the plants. 1- use some bennies if you have acess, Rechare is an example i know it works very well and covers many areas os issues like PH and nute Locks, the issue you have for instance, that will regulate vell your root zone so it can absorb well and is always estimulated. You can pair that with the cannazym, if you wish no woryes. 3-Keep the base nute and cut the boosters like Rhizotonic till the spotting stops, usually you aim for half of the schedule suggests and up slowly feeling the plant. I cant comment specifically on the Canna line. Also Make sure you are not aplying cal mag on every water if you use tap water, generaly one a week is enought to correct deficiencies. 4-use good watering habits, at the point you are you can water the base of the plant and a bit around, no need to soak the hole medium, it will take a lot to dry when its soaked and the plant ant brearh well or starts to sufocate. When is time to water you can feel the vase weight and the top os the soil sticking to the seccond knukle to see if is moist! 5-Check the runoff and see the EC that is coming out and PH, like that you will have an idea of what is in it. Good luck, happy growing!

I've been looking at your earlier pictures and data you posted. This is my take on your problem. What you have is nutrient lockout along with over-watering; plants that young won't drink 1 liter a day, a good practice is to water around the plant, irrespective of the pot size, at that age they might drink 200 cc per day. First and foremost your EC/PPM is to high since week 1, way high, be it because your tap water EC is too high or you are adding too much fertilizer. Cal-mag additives are used to bring soft water to an EC/PPM of 0.4EC/200PPM to 0.5EC/250PM. Your tap water is already 0.8 and you are adding even more cal/mag. You should not go over 1.0EC/500PPM in veg for coco and for seedlings it should be half that. Once you correct your EC/PPM you will experience better results. Try using bottled water as a base it will help

Try just raising the light it’s focus might be too intense for your plant causing the leaves to use more cal/mag than the roots can bring to them. Adding more cal mag will only burn the roots compounding your problem. Simple fix that if it is right you should see positive results within a few days. Best of luck with your grow

Just stop with all the nutrients... Too much form the beginning... Specially Rhizotonic... The dots on the leaves are from the excess of magnesium and calcium so just give them good water and let them grow a little more before feed them with all that nuts...

Oh no! that is the worst problem I have had which is Spider mites! check the underside of the leaf for white dots ( spider mite eggs) or black dots (live spider mites) and get some AZAmax and use it as a spray once a week for a few weeks

Just use plain ph 7 water , for 1 week , see if you can get RO water , then just use coco a+b , 1.5 ml per litre , Test the runoff ph and EC , its as B4Rns says don't fix with an additive , especially as your tap water probably provides too much calcium . My mate uses coco but I can't get on with it .

RHIZOTONIC 0.5ml / 1l ☝️ Your problem haven’t been solved bro. You’re using way too much RHIZOTONIC since beginning , trying to solved your problem with Cal Mag wasn’t the solution cuz it wasn’t the problem ... neither pH ... Now you’re having Cal deficiency because there’s too much Mag , when there’s too much Mag the plant can’t absorb Cal anymore . Stop the Cal Mag for a while ... and follow a Feed Water Water Water Feed Water Water Water Feed schedule and everything will be fixed . Happy Growing
