any updates on this guys? Clasic or Hydro with Calnit?

[blooper]

curious about this as well. i've been running maxibloom, tried the KISS method but 7g/gal was way too much. plants are doing fairly well vegging at 1.75g/gal but we're seeing calcium deficiency so i added a little calimagic. after reading some threads i figure it's because the calcium in maxibloom isn't fully dissolving.

just to clarify, the OP is saying if you mix the pro hydro 5-12-26 with the pro blossom booster 10-30-20 50% each plus calcium and magnesium and use at half the rate of maxibloom, it will be close enough to the lucas formula?

i like the idea of getting away from dyes and saving $..

1-2 grams per gal peters professional and Calnit
.2 grams per gal magnesium sulfate, potassium silicate, mono potassium phosphate, humic/fulvic acid powder

this works pretty well so far. if there is any amendments you would like to add feel free

Drop it completely or just lower it?

Edit: nevermind, should of read the next page before posting lol.

Just found out that you can buy calcium nitrate at a lot of farm stores, avoiding the high costs of shipping, and usually much cheaper.

Can you tell me what the poper feeding levels are for coco using the 5-12-26 and the 15-0-0 Jack's ferts?

One gallon RO water with 880 grams 5-12-26
One gallon RO water with 590 grams calcium nitrate (green house grade)

Mix these two in separate gallon jugs and use each at 10 ml per gallon of nutrient mix. PH to 5.8. I like the heavy arizona ice tea jugs to mix in. It may take a day or so for the jacks to dissolve fully so mix in advance.

Ten ml of each will give a EC of about 1.2.

Like to start a discussion about Jack's Hydro FeED 16-4-17 1 part hydroponic fert. At a 5 gm per gallon (hand jugs) feed rate, the cost is about .02 per gallon for fert and 1 measure of 5 gm, instead of multiple mixtures of 5-12 and cal nit. Has to be the simplest and least expensive option for hydro, outside of making the fert yourself. Have to replace Maxibloom (the previous simple option for me) because they are now owned by Miracle Grow (not long folks, before they change the recipe- ask old Peters users). Is there a
significant diff between the two formulations? Or does something need to be added to
Hydro FeED? One thing that bugs me about both is that both formulas seem to take the
opposite approach to N & P than Maxibloom. Maxi has low N and higher P, both Jack's
Hydro are hiher N and lower P. Maxibloom numbers were supposed to meet Lucas/Mel
Frank values- how off are the two Jack's formulas at advertised mix rates? Thanks in
advance for any help on this.

Thanks, but I'm a small grower. I guess I'll just divide accordingly to get to what I can use on a per day basis.

Get a one liter pop bottle and add 232 grams of jacks. Then get another one liter pop bottle and add 156 grams of calcium nitrate. Use 10 ml of each per gallon. Will get about 1.2 EC.
