My Plants are Sick :( - I think Ca/mag

[gardenfather]

Hey Fellow Growers.

So my plants "Were" Healthy up to this date.....

I've been growing them since May 21. Everything was fine up to the last few days. I started to notice the leaves were changing colors on me.

Does this look like it could be because of low levels of cal/mag?
please let me know thanks for the help

This is my setup

Autopots Xl
4 autopots
Nutri+ Nutirents
Led grow lights 600w

Last week I used my nutrients to feed my Plants.

I was using Nutri+ Nutirents.
I followed the chart

Now I emptied my Resevorse after seeing the health problems it's just filled with water and it's almost all gone. June 3rd I filled it with only water and now today it's almost all gone.

So I'm wondering If I should feed my plants when i refill my res and add some Cal/Mag to the nutrients?

Try it on one plant. Looks like Ca to me.

[FONT=Arial, Helvetica, sans-serif]Check out this recent threads at the top of this sub forum with exact same problems. The culprit is the Quantum Board or LED. It's really common for people who use QBs to experience cal/mag or necrosis/interveinal yellowing, respectively.

There are some good suggestions and mine are in there too. [/FONT]

I'm having a MG/Cal issue half way into flower under new LEds. Also make sure you're feeding between 5.5 and 6.5 PH. If you're growing in coco make sure you're getting adequate run off or the nutrients build up and the plant get nutrient lock and can't use what you feed it. Good luck.

Im using Autopots with soil and clay pellets. I lowered the lights added cal/mag so hopefully, it helps correct it. Next week ill be going into flowering.

I'm growing at the moment with some MarshydroTS600, got 2 of those to be exact plus a few other quantum board LED's. After using most types of lights out there I wanted to try the "white light" LED's for myself why I have several.
With the quantum boards my plants do seem to eat and drink more which means I'm feeding more. I have this plant in a 5 gallon earth bucket amended with organic nutrients. I did have to modify the earth bucket to hold at least a gallon of water which this plant gladly drinks every single day. I do add an organic calmag at least twice a week even though there is plenty lime in soil. Other than that she's rocking.
Begged for 2.5 weeks and put in flower. I'm actually kinda digging these "white lights".
Glue cross I made.

PEACE!

Same plant 1 week later.
She out grew the first 2 lights I had on her had to add another. Not white light but it'll work
PEACE!
