calmag citrate for mg deficiency

[Intronaut]

Hi everybody!
I'm growing 3x GHS sweet mango AF in a biobizz lightmix with biobizz nutes under 300w of leds.
Plants started showing mg deficiency (here's a pic) and it's getting worse, they're 19 days from sprouting.
I was wondering, can I give them calcium & magnesium citrate to solve this problem?
It's all I have right now and unfortunately I'm short of cash
Thanks in advance

Should work fine, but I can't help you with dosage. Good luck. -granger

Thanks friend, I used 1/2 teaspoon diluted in 500 ml of water, hope they get better.

calmag works fine, but be sure that all of the rest(ph of water, ph of soil, etc.) is dialed in before you apply it.
