I had more than a few plants and some tomatos.
I typically see a magnesium deficiency at around week 4 or 5 of flowering no matter what fertilizer I use. Thats when I start to supplement with a cal-mag formula and it basically stops. I was just curious as to why they wouldn't add it in the base fertilizer, but I get it now. If they did, a lockout would occur. Your better off leaving it absent and then dealing with it through supplementation rather than getting a lockout situation.

That is given to allow professional cultivators to know the potential acidity of the product....in other words given 1 ton of the fertilizer it would take 623 lbs. of calcium carbonate to negate the acidity of the fertilizer so that they can add and adjust as needed for the crop to achieve proper ph for the crop..there is no calcium carbonate in the fertilizer
If you feel that calcium and mag will be needed as you are running ro water or such then might I suggest looking into this:
http://www.dyna-gro.com/
Contains EVERYTHING needed in one formula...
Hope it helps

I'm not sure if I would want to go with the dynagro because it DOES have calcium. This may cause a lockout if you apply it before it is needed. Is my thinking correct? I guess it depends how quickly the dolomite lime breaks down and makes those micro nutrients available. Maybe you could use Jacks classic till it becomes an issue and then start using dyna gro??

I would say that's fairly accurate. Dolomite lime is very slowly available to the plants. Often it's not enough Cal and Mag but sometimes it is. The finer the dolomite lime, the quicker it's available. Strain, soil, water and type of nutes will all play a role but Calcium and Magnesium deficiencies in cannabis are both fairly common. IME it's always better to add salts than it is to try and flush 'em out. I'm pretty sure riddleme uses a combination of Jacks and Dyna Gro in soil. I'm not sure I'd go with straight Dyna Gro in soil but he gets pretty good results using the 2 intermittently.
You can tell pretty quickly whats going on. I am upping my ppm's every feeding so when the lower leaves begin to yellow its obvious its calcium and magnesium. I must say though, I was not always aware of this and didn't supplement a few times and suffered dearly with massive amounts of dead leaves and I had no idea what was happening.

i am so happy i found this thread because i was wondering the same thing about the calcium and whether or not i should supplement. really great info about the potential for lockout. i'm switching from fox farm bloom nutes to jack's classic for this grow. i still have a ton of ff grow big so i will be using it for veg still, and i also plan on conditioning the soil with big bloom throughout the whole grow. i was concerned about the lack of calcium but i noticed none of my nutes have any. good stuff here.
calcium is wat packs the punch in the bud.u can add lime to soil and calcium won't be available if plant is being over watered.Don't they ask what plants you will be growing with your "custom fert"? That would be the only drawback I see to this. Very interesting though, very interesting indeed.
ph can be in the higher range of ph if planted in large pot because it takes longer to drain,moe buffering capacity.this is taught in college,not that i went,just saying.peace clone2/help others put back from which you have taken..peace
shake and feed is available with calcium,just like osmocote except it dosent hav a high ph.wen shake and feed mix with tap 7.4=ph 6,mix ph 7.4 with osmocote and ph goes very high.shake an feed cheaper to has micronutrients @homedepoe.lik also natures organic beding soil,has worm alfalfa in to name a few and pro-mix in 320z cup shake an feed add small sparse skimpy teaspoon,no drainage holes,weigh it dry,add 6ounces of water poured down the center don't mix.plant seeds shallow.water wen it weighs less then the dry weight or = 1/4 to 1/2 inch dry down in soil.i use ounces scale wen it weighs less 1/2 ounce then dry weight to start=1/4-1/2 inch down dry in cup.plants tak up moe water big plants that have water roots that can take up loads of water.i like it better then hempy bucket cuz i can b around to water that much.just a saying..

If you actually read my threads you'd know I never do that, I merely share things and what folks do with the info is up to them.
