Magnesium deficiency

[Awg52]

Hi all, kinda narrowed down the issue with the banana blaze, stems are pretty much all red/purple colour. Along with a few other indicators it looks like a magnesium deficiency

Anyone any advice to fix magnesium deficiency in bio bizz all mix soil? I’m using bio bizz nute range aswel

1/2 teaspoon epsom salt dissolved in water and/or next feed. only a suggestion, do your own research.

ive had a look online but it’s information overload lol just wondering if anyone’s experienced similar and what worked for them

I've been adding 1/2 gram to my MC 1 part asI've seen suggested and haven't had any more problems in that area. Look into MoG's posts as he's been doing extensive research into nutrients.

are the stems purple entirely or only where they are getting light? I get that with my cob lights.. the portions of the stems getting direct light will turn purple.. and there is no lack of magnesium when it happens...Pics would be helpful

Looks like you either have a ph issue, or a deficiency. Overall they look hungry for P and K mostly or the medium is out of whack and they cannot access the nutrients .. What are you growing in? What are you feeding? Are you using a ph and ppm meter where applicable?

Yeah had a previous thread on the infirmary page, soil is around 6.5ish, grown in biobizz all mix , nutrients biobizz range as per schedule but half strength.
I flushed her out about 4 weeks ago as thought the original issue was a lockout, she was flushed so run off was around the 6.5 mark.
