I have a 60 liter tank for automatic water. Tap water is ok here, drinkable from the tap. Besides i add dechlorinating for fish. Should i use those concentration of calcium and magnesium in the 60 l tank or water the plants once a week or two manually with those ammounts?Looks like u sprayed something and that might have been to strong. I could be wrong.
Otherwise, what's your tapwater like and how much calmag do you add to it? At your plants stage I'd probably target the 120mg/L of calcium and 40mg/L of magnesium mark.
And in full flower around 150-180mg/ L calcium and 50-60 mg/L magnesium.
Thats just a rough guide..it really depends on your lights strength.
For example.. With 800w LED that won't be enough..but for 400w HPS its probably too much already.
Just look it up online. You might be surprised what you find out. Sometimes u gotta do nothing, Sometimes u have to adjust with calmag. Worst case scenario would be if u need a Reverse Osmosis filter.I have a 60 liter tank for automatic water. Tap water is ok here, drinkable from the tap. Besides i add dechlorinating for fish.

Interesting idea. There is some downward cupping often associated with an over feed. The one growing point I spotted as almost stopped with strong Fe signs. Some of the leaf pics look like simple burn. Others Ca. Some look strange enough to be an outside attack, but for now less feed looks best.Looks like K excess to me, which causes Ca, Mg, Zi and Fe deficiency.
How do i solve the problem? adding dolomite should be enough? or do i need some specific Ca:Mg ratio? yesterday i stopped watering and tomorrow i'll check the soil if its dry so the plants can intake the minerals when i water. I will test pH tomorrow, which range should i expect?Looks like K excess to me, which causes Ca, Mg, Zi and Fe deficiency.
Where can i find that light related cal/mag ratio information? seems interestingLooks like u sprayed something and that might have been to strong. I could be wrong.

I got these from the water suplier, cant find any Ca or Mg on the report. Sorry its in spanishGet a water analysis report of your area,usually u find those online at your water supplier homepage...see what's in it excalty and adjust to what you need(3:1 ratio of cal:mag) If the problem keeps coming back its not that.
Besides that it makes sense to check leafes with a microscope for parasites.
Any other nutes used except what was mentioned before? The more info you give,the more help u can get. Thise spots could also happen if you overwater and so on.. its a complex topic. Full shot in the dark with flash makes it easier to see what the plant is really up to.
Good luck for the rest of this run,stiff
Does it give a hardness value? That's usually a combo of Ca and Mg.I got these from the water suplier, cant find any Ca or Mg on the report. Sorry its in spanish
