Plagron CalMag recommended dose?

This totally depends on how much calcium and magnesium - 2 unique and seperate elements of nutrition - in your other products added for fertilization. Are you in soilless or hydro? This is much easier. Probably want about 75 PPM of Mg and 100+ ppm of Ca. With RO water, maybe a bit more of each. In either case, thise would be a good start and very small fine-tuning adjustments from that point on. Ther are apps that can calculate this tuff from your gauranteed analysis labels and dose. soil is more complicated. there are likely amendments releasing ca and mg over time. you need to supplement that and it takes a lot more trial and error and less specific suggestions can be made. watch for symptoms and keep track of how much you provide over time -- fertilization is about months of time, not what you did last night or last week. The point is if you already provide some Mg (very likely) and some Ca (less likely due to precipitate issues combining it with other stuff at high concentrations), you may not want a full dose of a ca-mg product. The cumulative total yuo proide over time is what matters, not tunnel vision with 1 component of your fertilizer does it have symptoms of Ca or Mg? again these are 2 different things. Calcium def is spots on their own. Mg def is intervienal chlorosis with spots that are a different color, usually. Mg deficiency takes 30+ days from start of the lack of Mg to the point you see symptoms in leaves, whereas Ca deficiency will occur much sooner after it becomes deficient. the way people lump them together makes me doubt what they are saying and their interpretation of the symptoms. these are not the same thing. just because 1 product comes with both doesn't mean shit. they don't even bond directly to each other, lol, they are both positive ions (cations). They are unique elements of matter with different functions in the plant. i've never had to use cal-mag because i use calcium nitrate and epsom salt (Mg and S). I would never use that diluted overpriced trash product, lol. what is it 1-3% of each? just buying overpriced hard water, lol.

Hi, For Plagron CalMag Pro, the recommended dosage is a maximum of 1 ml per liter of water Since you're using 0.7 ml per liter, you might want to consider increasing the dosage slightly to see if it helps with the deficiency symptoms. CalMag deficiency symptoms can include yellowing leaves, browning leaf edges, curling leaves, slowed growth, and weak stems. Given that you're using RO water and LED lighting, it's important to ensure your plants are getting enough calcium and magnesium, as LED lights can reduce plant transpiration and nutrient uptake. Try adjusting the dosage to 1 ml per liter and monitor your plants closely for any improvements. If the symptoms persist, you might want to check the pH levels and overall nutrient balance in your growing medium
