Coco grow Ugh issues

Coco issue

Root farm coco I rinsed with 1/4 strength maxibloom and 1 tsp of cal magic


Seedlings 13 days from sprout. R/O with 1/4 strength maxi loom 1tsp Cal magic 6.0 ph under 4 T5 shop lights
Plants iN garage and off the floor but def been under 60 degrees at night. I have been watering every other day to run off and my roots seem to be filling the pot now. I believe I have some kind of decency.
I do have another plant 8 weeks old not looking great but here are some photos of the seedlings for now. I apologize any bad grammar using my phone

Your seedlings look fine to me. But maybe I am just to high and missing something.

I see a little tip burn...maxi bloom should already have cal mag. Maybe go a little lighter on the feeds. Looks fine though.

Too cold at night.
Try tap water instead of ro and ditch the calmag.........I never have to use it.

They still look nice and healthy for now but adding the extra Cal/mag Is gonna cause you K deficiency. you have it in the maxi bloom has it already.

Mick nailed it, warm them up and ditch the calmag. Are you using RO for a particular reason? Tap water would be better unless you have some sort of extreme water. Do you have a TDS meter?

I do have a TDS meter not sure if it reads
.5 or ,7. I tested
My tap water and says 957 PPM. I had a few successfully grows with tap water but I never checked the PPM before this time so I changed. I used to use
tap water and 1 tsp of calmagic and water once that way then the next just 1 tsp calmagic and they looked healthy. So last night I added 7 grams
Of maxibloom to my tap water and metered reads 2045 PPM.

Way too high if you ask me. But the plant looks fine in the pics

There's a 40% difference between a .5 and .7 scale, would be a good idea to figure out which. Yet another reason to stick with EC; its unambiguous.

957 ppm on either scale is off the charts for tap water.

i hope you dont drink that water

I'd dial back the cal mag to 1/2tsp. People claim to never use cal mag in their coco grows, but i get "tiger striped" leaves almost as soon as i stop using it. Granted i buy the cheaper coco, but still. Cal mag is definitely useful in coco grows.

You or your plants may gain some mutant powers by drinking from the tap. You're just going to sit there and use RO while criminals overrun your city?

We get are water from a local lake here and with the drought it seems the water has gotten worse and worse. Most people in my town have water softeners. I drink it out of the fridge filter and I’m okay I believe lol

Not using tap water at the moment. I just wanted to do a test and see what fill nutrients would be.

check the tds after you put it through the filter your numbers are just about twice the EPA's allowable tds for drinking water. you'll be okay until you have a baby growing from your neck

My tap water was reading 300ish ppm and I was having problems with first grow. Got an RO system and everything went much smoother. Probably dont want to be using that tap

If I keep on using R/O should I cut out the calmagic?

Everyone I appreciate the help. I wil go home tonight and check what TDS meter I have and get back to everyone. I will take some photos of my 8 week old plant that had some issues and stopped growingfor 2 weeks

Do you use calmag with your R/O water? If so how much?
