Hey all.
Hopefully someone can tell me wtf is going on here. I have recently switched to using ro water and are still having problems with mag deff showing up.

Im using cal mag at 5ml per gallon to get it up to 200 ppm then adding canna veg a and b to total 700 ppm.

I'm still getting some yellowing of leaves with this ppm which I imagine would be sufficient at this stage of the grow.

Anyone got any ideas or solutions.
Cheers

what is your ph at? have you had fluctuations in ph?

Ph is set to 5.8 and never changes if anything it will go up one point to 5.9 over 1 week between water changes.

Say she is drinking 5ltrs of water in 5 days should I be topping her up with water and or water/nutes or just leave her alone between the weekly bucket refils?.

Thanks although ive always had worse problems with my city water.
I know ro water is lacking a few minerals but isnt cal mag enough to supliment it?
I'm due for a bucket change Tomorrow so I'll bump my ppms up a couple hundred.

Gradually up the ppm, but don't slam her with doubling the dose right off the bat, it does look to me like n deficiency, but a lot of things mimic other things. Try 800ppm, then watch for changes, if all is fine at 800 bump it up to 900. And so on.
