There is your issue. My tap water causes all kinds of leaf spots which is why I use RO. If your 'fix' is calmag, then that's certainly easier than running an RO setup but that still doesn't mean the food is to blame in your case.Tap water yes. I agree with you, dynagro supply all the elements needed but it doesn't mean you have enought of each elements. Glad for you if your not having this issue.
I'd love to see some pictures of some plants at harvest that have been fed 11mls/gal. That's wicked strong, IMO.
Okay, are you trolling? First, you filled out that calculator/Nutrient Profile incorrectly. Second, said calculation was done at a feeding of 15ml/gal (!!!) and then you say you never feed over 11ml/gal? What was the point of the 15ml calculation. Please don't mislead people.
this was fed on my motherplant. it's not that strong , only too much N that's it. It wont kill your plant in hydro except if you keep feeding them this dosage.They ran like 2-3 day with this mixture and was lightly affected. this say, my motherplant is 4'tall and 4'wide, not small plant.
Where is this 'optimal dose' of magnesium coming from? I have the lab data and know for a fact that in hydro our plants don't use a lot of magnesium. If you fed your plant 30ppm of magnesium, 25ppm would go down the drain at res-change-time.
Why you put all the blame on my water? You think dynagro formula are perfect? sorry but they're not. One part formula can't be as complete as two part formula for obv reason.Their one part is still the best one part.Like stated previously, I'm glad for you if you're not experiencing mg defiency.
I use an RO filter and when the ppm of my RO water gets up to about 60-70ppm, my plants will show signs that it's time to change my membranes. I'll start getting funky leaf spots on my plants making me think of the ever-so-popular issues on these canna forums like 'pH' and 'cal/mg' when in reality it's just my sh*tty tap water rearing it's ugly head.
Nothing is official at IC Rag. It's just another forum with a lot of newbie bullshit, witness your link.....and this recommendation - "The plants can be foliar feed at ½ teaspoon/quart of Epsom salts" Ridiculous. That will not only induce a toxic issue but severe leaf burn.
I've seen you post about using rain water before but how often are you using your well water on your indoor plants? I suspect it's my bicarbonate content but my plants cannot take my tap water.
Have you ever looked at your comprehensive chemical analysis on your municipal tap water?
