    Magnesium and Potassium Lockout due to too much Calcium?

    Again I don't use calimagic. I have used CalMag Agent from Canna. I DON'T use Cal/Mag at all right now! Now I use Epsom Salt instead of Cal/Mag. And the CALMAG AGENT from CANNA has different dosage recommendations than your CALIMAGIC. The last res I mixed like this: I started with distilled...

    Magnesium and Potassium Lockout due to too much Calcium?

    I know it does but I don't know how much of the EC is N. You only use flora nova bloom? So just like the lucas formula? Do you grow with LED (people say it needs more calciusm/magnesium) or what light do you use? So you think EC 1.3 base nutrients is still not enough and I should use even...

    Magnesium and Potassium Lockout due to too much Calcium?

    I only use base nutrients and a little epsom salt right now. I think it's working better than before! I don't use ANY Cal/Mag right now because all of you told me to ditch it and use base nutrients only. But even with base nutrients the deficiencies kept going so I've added epsom salt like...

    Magnesium and Potassium Lockout due to too much Calcium?

    I measure EC daily too and add acordingly. If EC raises I add only water and lower EC. If EC lowers I add more nutes. If EC stays stable I add water with same EC nutes as in res.

    Magnesium and Potassium Lockout due to too much Calcium?

    I think we talk about different Cal/Mag products because as I stated in the post you have quoted I say "On my bottle it says to use 0.1 - 0.5ml/L until EC 0.45 is reached. And I need 0.8ml to reach 0.45 EC... And when I still got deficiencies I started using 1ml and 0.58EC." I use MORE than...

    Magnesium and Potassium Lockout due to too much Calcium?

    2/2 Text goes on! I started to even calm more down. From 01/17/2023 on I used only base nutrients but this time I increased the dosage to about 1.08 EC only base nutrients (because no epsom salt on hand how people recommended) Fast forward a week I got my hands on some empsom salt. After...

    Magnesium and Potassium Lockout due to too much Calcium?

    I grow DWC hydroponics. First time problems like this. But I've switched to a high power LED light. I've read Calcium/Magnesium is a LED problem they need more... Anyway idk. Nutes I use is General Hydroponics Tri Part I use distilled water My step-by-step of adding nutes is this: I take...

    Magnesium and Potassium Lockout due to too much Calcium?

    Hi I'm back! I was following @Rurumo 's advice and the plants grew a good amount in the last 1.5-2 weeks. It took some time to get my hand on some epsom salt and I was adding it slowly day by day because I was scared of overdoing it again. I think the deficiencies are progressing slow now (or...

    I'm overwhelmed. Questions about Reservoir-/Nutrient-Management and how Plants take up Nutrients.

    Thanks for the reply! I also think I was overthinking it... I'm sleeping better since I calmed down lol I do the same when it comes to EC but I'm still a little bit confused about the right feeding amount. Especially after adding extra Epsom Salt because my plants are very deficient. I think I...

    Magnesium and Potassium Lockout due to too much Calcium?

    Mine went bad pret1ty fast and I was adding more and more Cal/Mag... One plant is as small as a 2 week old plant or something like that! But still alive that's a good thing lol Thanks for wishing me luck. I hope it goes well! Right now it looks ok! Thanks! I'm following @Rurumo 's advice right...

    Magnesium and Potassium Lockout due to too much Calcium?

    I think it is an excess of calcium too! Because I was feeding a lot of magnesium and still got problems! And checking deficiencies it looks like Magnesium deficiency and also looks like Potassium deficiency (dieing leaf tips and edges).

    Magnesium and Potassium Lockout due to too much Calcium?

    On my bottle it says to use 0.1 - 0.5ml/L until EC 0.45 is reached. And I need 0.8ml to reach 0.45 EC... And when I still got deficiencies I started using 1ml and 0.58EC. So yeah I was using too much... maybe 0.2ml would have been enough with enough base nutrients. Some days are over now I...

    Magnesium and Potassium Lockout due to too much Calcium?

    Damn thank you! Looks like calcium is able to lock out a lot of nutrients! Saved it! And I think I used a LOT before! I think I'm on the right track now only feeding base nutrients. The leaves don't feel as dry as before now. Maybe I will add just a little bit Cal/Mag later if she show signs...

    Magnesium and Potassium Lockout due to too much Calcium?

    I had zero problems with distilled water yet. I also aerate it so dissolved oxygen shouldn't be a problem. For some people it's hard to test when it's still pure but as soon as the nutrients are added there shouldn't be a problem. At least I don't have a problem testing it. Maybe different...

    Magnesium and Potassium Lockout due to too much Calcium?

    Changed the reservoir yesterday. Just base nutrients and no Cal/Mag. EC 1.08 PH 5.8 Will keep an eye on the plants if symptoms get better or worse!

    Magnesium and Potassium Lockout due to too much Calcium?

    I use this product Canna CalMag Agent (https://www.cannagardening.com/calmag-agent) I use 1ml per litre so converting it would be about 3.8ml per gallon (US Gallons). Instructions on the bottle say to use 0.1-0.5 ml per litre to reach EC 0.45 but I need 0.8ml to reach a EC of 0.45 with...

    Magnesium and Potassium Lockout due to too much Calcium?

    I grow with DWC. Only water in the reservoir. Ok you think 1 to 1.2 EC is not too much for a smaller plant? I was thinking about just using the base nutrients too so I will change the res soon and add only the base nutrients and will see how that goes! Thank you! Edit: And since there is no...

    Magnesium and Potassium Lockout due to too much Calcium?

    I've still problems with my plant and it's not over yet. I've read that too much calcium can lead to other nutrients beeing locked out. Since I have problems with my plant for a long time I start to think that this might be the case. I'm adding more and more Cal/Mag over time since it was...

    Need professional help identifying the deficiencies

    Every time I don't add Cal/Mag I get deficient plants. So at least I need some Cal/Mag in my water.
