Confirm CalMag Deficiency??

[jackogpush]

My babies 2 weeks vegging are yellowing a bit from the outside of the leaves in. I suspect Calmag deficiency. Can any experts out there confirm or chime in. My Ph is a consistent 5.9 - 6.1. Growing in rock wool mini cubes.

Im feeding at 600ppm with:

1 part Cal Mag
3 part Pro Grow
4 part Diamond Nectar

The 1:3:4 Recipe was given to me by an expert grower friend. Seems to work well for him but he hasnt been available lately for advice so looking for a 2nd opinion. During bloom I use GH with good results

definitely calcium deficiency....

many posters before me suspect nitrogen. but if you look at the stems of the plant and the stems to the fan leaves, they are purple. that's an indication of calmag deficiency, most likely from the wrong ph....

this is common on clones that have been sitting for a while or off of "woddy" mothers....

your new growth is a healthy green and continuing with your higher ppm, is most likely correcting your problem.....

wow! i just saw your little nutrient/additive mix. if your using gh in bloom, use it in grow and DO NOT do that mix that your expert said to use, its definitely suspect in your lockout....

in veg they just need some simple nutrient, that all. using calmag every time will lockout other macro nutrients. and diamond nectar is decent, but mostly used for bloom.....

Thanks for your 2 cents. I greatly appreciate it. You really dont think that this brand is a good one?

that's good stuff, but i thought you said you use gh in bloom. just wondering why you would change nutrients like that. gh is cheaper...

but using the additives like what you mentioned, will cause lockout, stick with just your base nutrient right now and watch them blow up!
