CalMag Confusion?

[basssc]

Hello dear friends.

I water my plant twice a week, once every 4 days. I am feeding my plant GrowMicroBloom + big bud. I apply these fertilizers once a week as feeding chart shows. Other days i use simple water. I mean 4 days with fertilizers 4 days with simple water. One of my friend said and also i've seen somewhere in internet "You can use CalMag with simple water". I am confused a bit.. Bcoz one of my fertilizer bottle (micro) has Calcium and Magnesium already. I put some photos here and i need your valuable eyes and experiences. Should i use CalMag? Thx...

INFO ;
-Plant is 25 days of flowering
-Every watering i apply 4L
-I use coco peat + biobizz lightmix soil with 26L fabric pot
-I apply 13h dark, 11h light

Welcome to 420,basssc
Can't tell from that pic if it needs a shot of cal-mag or not-(if that's what you're asking) can you get a pic in natural light? (without the blurple)
Is "simple water "just tap water?

Hello friends. Here are clear photos



I am using drinking water, not tap water. Tap water has chemicals like chlorine... Therefore i use drinking water. i also noticed that there is no Calcium and Magnesium on the table of chemical analysis of the drinking water.

That doesn't look like a Mag def to me. I don't see the tell-tale red stems.
There is no burned ends or edges of leaves, so I don't think it's over feeding.
I don't see any signs of pests, but I'd want to scope the underside of those leaves and look for aphids.

Get a scope and look under those leaves.

Seriously, to me, it looks like over watering.
Is the medium dry or dryish when you water?
Do you only water when needed - or on a two day schedule no matter what?

It’s because they are not regulated contaminates by the EPA under the Clean Water Drinking Act. Some utilites will list the total hardness of the water supply, which is mainly comprised of calcium and magnesium but does potentially include other similar elements that contribute to water hardness.

Why do you not use city water? Little chlorine isn't going to hurt the plant. Are you can let the water sit out in the chlorine will dissipate in 24 to 48 hours.

I don't see a calcium or magnesium deficiency. I agree with Auggie cold be over watering what are you temps?

Yea yea.
Temp stress will cause that clawing.

Overwatering or overheating.

That's my final answer.

Could be too much wind.
Or too much nitrogen

But usually when the entire leaf is just one long claw its usually way to much wind.
