Adding Cal-Mag to hempy bucket feeding?

ns420 · Mar 10, 2010

Hello,

I have some Alaskan Ice clones in Hempy Buckets, approximately 2 weeks in veg showing magnesium deficiency on some of the older leaves.

The clones are showing decent growth, and the newer leaves are not showing deficiencies.

I decided to add Cal-Mag to my normal feeding, which is currently General Hydroponics Flora Series, 5-5-5 (5ml per gallon of FloraGro, FloraMicro, and FloraBroom), and was curious how I should go about doing it?

Do I need to cut down on other nutes when I add the Cal-Mag, and how much Cal-Mag should I add per gallon?

Has anyone had any experience with using GH 3 Part along with Cal-Mag in a hempy bucket or hydro setup?

Also would there be any benefit to adding Superthrive to my veg feeding? I was told by a friend that it would help with nutrient uptake and overall plant health. Is there any truth to this?

Thanks in advance for any and all input

Are you adding the micro grow first to the water?

Yes I do, why do you ask?

Nutrient lockout. I thought for GH and vegging it's a 3-2-1 ratio of Gro/Micro/Bloom.

Yeah I add the MicroGro first, to avoid nutrient lockout (as was instructed on the bottle). I read that Hempy himself says to use 1-1-1 GH 3 Part for veg, so I was going by that and since switching to GH3 Part the new growth looks perfect. However I am always open to new ideas on how to improve my results!

I believe the deficiencies where caused by the fact that for the first week I was using Fox Farm Grow Big that was formulated for soil, and not hydro.

Anyone have any advice or suggestions?

Hi mate, I am currently in a similar situation. Just started flowering in 100% perlite hempys and throughout veg had troubles with magnesium def. I begun using epsom salts, rather than cal-mag as my water is hard; high ca locking out the mag. I believe it is improving.

I do not think you have to adjust your nutes in relation to cal-mag, the ppms of cal-mag are low and only relative to cal-mag i do believe..

If its a magnesium deficiency though, perhaps epsom salts would be better? are you using r/o water?

maybe ph lockout is causing some of the deficiencies? do you let it swing? what is your ph?

What medium are you growing in?

I used the GH Flora Series DRAIN TO WASTE formula, and it worked great at Full Strength, even had to up it a little- http://generalhydroponics.com/site/gh/docs/feeding_sched/GH-FloraSeries-DTW-Charts.pdf

I ran 100% Perlite Hempy's with this, and they grew perfectly without any CalMag.

I now run Coco Hempy's and use CNS17, and nothing else.

Good luck!

Hi NS420,

I use GH Flora in my Hempy's, WORKS GREAT! ... I use the Plant Magic 'Magne/Cal' brand. .... I use it at 0.5ml per litre. Its great stuff to add. I add it after my 3 part.

Thanks for the replies but I posted this topic 3 years ago... since then I have switched to Lucas Formula and have not had a single deficiency issue since.

If they want 'current' Hempy threads to include they could have moved the ones in my sig.
