Possible magnesium deficiency?

[trace-monkey]

After searching the internet for a few hours i came to the conclusion they have a magnesium deficiency, but one of the leaves looks like it might have a nitrogen deficiency... could anyone please help me out here? lol

It's a soil grow, about two months (maybe abit more) into veggin. They're under a 300 watt blue cfl, been giving them 2 ml bio-bizz liquid plant food per litre and sprayin them once a day with 5 ml of nitrozyme per litre of water. I have also been battling spider mites since i had them.

What i can see from the pics is your plants are needing more feed as look at the purple colour
in your stem aswell as the dying of leafs and that shows me there more than 1 nute problem
here and your soil will have no nutes left in it or next to none after 2 months.Bio bizz feed is a
pain in the ass if you ask me as i use canna now which is easy to use and you get great results
but that just me but i would defo start upping the dose of feed and they should improve .

Good luck with your grow mate and check out my diary and see how i do it.

Looks like Mg and N def, for sure. Give calcium, magnesium and a good balanced fertiliser.
