PPM is around 900-1000, pH is at 6,0 according to the water test kit.

So maybe a little high,what is your water?

Just hit it with the CaliMagiccccc

@myke agreed, maybe around 600-700 ppm right now.

Cali-magic or hydro products aren't exactly available locally where I live, like over 100 kilometers is the closest one... Can I grind up calcium supplements I can find in the pharmacy instead?

Edit: I somehow added this to an earlier reply I was writing about the fact I live within EU and in a country where misleading lables are considered a severe fraud, the label also says that they're manufactured in the EU. I'm not saying the deficiency isn't a possibility, since every strain and system of growth has their quirks, but I highly doubt that AN can pull 'muricah level of businesses savvy/scumminess

you can use Epsom salts for the Mg,about 50 ppm.Ca should be enough in your nutes.

Good to know. What'd you think of the size of the plants or should I let the girls grow more? The tent is 60x60x120cm just for help. They're about 13 centimeters tall and each already have 6 flowering sites, for size reference the lid of the reservoir of 51x40cm. Would I get a decent yield from this? Master Kush has a flowering time of 7-8 weeks.

You want healthy plants before you switch,lets wait and see what your new pH does.your ppm should drop a little ea day and your ph should rise.

Well, here's an update of sorts... Got epsom salt, added a teaspoonful of it into the current res water, can't change the water because my exchange pump is busted and can't get a working one until tomorrow. Today was hectic, so I felt I should at least throw shit at the wall and see what stuck, first being the spoonful of epsom salt but since the coloring of the leaves is NOT ideal and most likely sign of calcium deficiency that was agreed on, but since not one soul told me what to do about that without cali-mag as an option I was forced to take a little of the reservoir fluid into a misting bottle and spritz that onto the leaves as emergency foliar feeding...

Seriously though, I asked if I could've used pulverised calcium supplement tablets from the pharmacy as a way to curb it until my order of cal-mag comes in, which might finally arrive this Friday.

So yeah, here's pics of progress.

TL;DR
Busy stressful day, threw a spoonful of epsom salt into the res, water change pump fucked, sure looks awful lot like calcium deficiency, cal-mag comes by Friday probably, help or I'll play chicken with the traffic if my plants die

Oh and pH is at 6,0 I think. Still using the aquarium test kit, ordered a proper meter today

Does your ppm drop in 24 hrs?Watch new growth the spots arnt going away on the old leaves.The nutes you have at 1000ppm is lots adding other stuff only makes it worse.be patient,again did your ppm drop?and your water level did it drop also??

what is the ppm of your water before you add things??

Chopping up calcium supplements pills I’m not sure on. I’ve looked before at adding them but wasn’t convinced it was the right thing to do.

Okay, I managed to switch out 10 liters with a manual pump and got the PPM level down to 790. The PPM level itself didn't change that much from yesterday, but the girls are drinking water since I have to top off the reservoir every couple of days. After the 10 liter switch of clean water the pH is at 6,5 but I'm going to lower it to 6,0 as soon as my wrist stops pulsing with pain from using the manual pump... Also, in terms of the calcium I'm hoping to curb the deficiency with foliar feeding if it comes down to it until the additive arrives in mail. But thanks for reminding me to keep an eye on the newer leaves for changes

That’s a good sign that your ph goes up. Nice work!

I just assumed that the pH changed from changing 10 liters of res water. It's just an hour till lights out, should I adjust the pH at this point at all or leave it like that until the morning?

6 or a hair lower is good. Post a pic of the color in test sample

Here, this is probably the greatest problem maker. Not exactly accurate to a decent range I imagine

With my ph pen. I get just a hair of orange yellow at 5.8.

Well, once I get a meter I'm going to use that until the damn thing rots to subatomic particles and get a new one. I hate checking pH like this... The rough numbers are just bad craftsmanship.

Any thoughts on practicing foliar feeding with the reservoir fluid until I get the cal-mag additive?

U could dilute your res water down to say 100 ppm. Then the epsom At 50 ppm. To foiler. I’m not the pro at foiler thing. Do some research first.

Well I'm going to see about that tomorrow, since it's a matter of micro nutes I'll make the foliar feed separately with the micro maybe at 100 or perhaps a little less but add a full brunt 50 epsom, foliar feeding is surprisingly effective so I'll spritz the plants around 3 times a day at first and increase the rounds if the deficiencies start to show more.
