What’s your EC in now versus EC out?I just fed them now at 1.5ml A 1.5ml B and 1ml calmag... see how they are tomorrow... everyday I'm learning shit... thanks bud

Ph was a perfect 6 EC was1567 ppm was 769 letting them drain for a min then ill measure run off..

1567 ppm? What calibration scale are you using?
In relation my plants are 2ft tall fully flowering and are receiving less than 500ppm at .5 and 700ppm at .7 calibration

Sorry... ph was 6....after all nutes.. the EC was a high 1.5 the PPM was 769

Ok so you’re running at .5 ppm scale when you reference ppm.
seems rather high EC.
What EC is your starting water?

To be fair I never measured it....

You need to know what it’s starting point is.
soft water 0.2-0.4EC
Hard water +0.4EC.
Hard water usually requires some form of treatment or nutrients that are less in Ca and Mg (hard water versions)
Soft water usually requires additional Ca and Mg in nutrients (soft water version) or Calmag product.
my water is 0.2EC considered soft. I use soft water nutrients base A/B and additional Calmag.
you need to know what the EC is of your water.

Run off from 1 lsd
I have hard water so got the HW version

Didn't get any run off from the white widow so I just boosted her with a little phd water til she flushed ever so slightly... gonna start a separate feeding schedule for her as shes not taking as much as the lsd's

You need to stop just giving ph'd water. They need nutrients daily

Fresh nutrients
You're in coco, feed and water daily. You can not overwater coco. If your water really is in the 690ish range consider RO. Red stems are a P, cold or genetic issue and have nothing to do with Ca/Mg def and with 600+ water that won't be your issue now. Listen to @jondamon he knows what he's doing.

I'm listening bud... unfortunately I done and posted without waiting for a reply... my bad... I did look into the red stems and I've seen it on a few lsd grows so not overtly worried about that...
Thanks for the info.. much appreciated..

Ok so I'm gonna start giving the nutes and calmag daily at current rate... should I give 1 litre each??

No my point is that your water is hard already which usually means you’ve got enough Ca in the water source hence why HW nutrients have less Ca and Mg In them to compensate for increased calcium in the source water.
I always ask what source water EC is for anyone who’s using coco as this is vital.
I’m pretty sure I asked more than once for the info but you must have over looked it til earlier.
Feed every day now but hold off on the CalMag as I’m not sure you’re going to need it with your starting water at 325ppm on the .5 scale which is around 0.6EC. Plus Ca and Mg def early signs are easy to spot.
most nutrient companies say with source water above 0.5 then you should consider an RO system.
but hey ho.
Do me one favour and start posting in only one type of measurement scale as you’re confusing the hell out of me with both ppm and EC lol.

Probs about 3/4 ltr. Wait 5 mins see how much run off you get, if only a bit then water bit more.

Fwiw. I have just started using quantum boards with lm301h. Plants showing lack of cal/mag. Upped the dose 5ml and responded well. Also dimmed down to 40% from 60 if that helps
