does this look like Mag?

Temperature is another important factor which influences root growth, as well as the absorbtion of water and essential ions. The optimum root temperature will vary some with plant species, but in general, root temperature below 68 degrees (20c) begin to bring about changes in root growth and behavior. Below optimum temperatures reduce growth and branching and lead to coarser looking root systems. Absorbtion of both water and ions is also slowed as the permeability of cell membranes and root kinetics are reduced. Translocation in and out of the root is equally slowed...When root temperatures are low, plants will wilt on high atmospheric demand days, and elemental deficiencies will appear. Ion absorption of the elements phosphorus, iron, and manganese seems to be more affected by low temperature...

yo sproutco, I set the chiller back to 67 which should keep the temp between 67 and 69. I also added some Hygrozyme in place of the hydrogaurd. The Hygrozyme is supposed to be the shiz-nit (should be for the f'n price!).

We'll see what they do. Despite the problems, they are still growing noticably each day and the roots look fine. I also gave a foiler of PBP grow last night..

Where do you get that zinc foiler spray you mentioned? is it from the grow shop only?

 

[sproutco]

I think the higher temps and adjusting your nutes will be plenty. No spray needed.

Sproutco,

They're looking MUCH better now. I'll snap some pics tomorrow. Most leaves are turning more green except for some of the ones that had the most progressed deff. Almost all of the leaf twisting is gone.

For flowering, I plan to run PBP bloom, Liquid Karma, AN Big Bud, and some mag suppliment (maybe sweet, cal-mag plaus, or epsom salts).

I'll run them through the calc to see what ratios fit the mel frank profile. One thing that may make the calculator more acurate is having the exact weight per ML of each nute (I don't have a scale). It also seems strange that all the nute mixes are lacking significantly in P.

Check for some updated pics tomorrow. laters..

 

[seek_UP]

How about this:
(all amounts are per/gal)
12 ml PBP bloom
10 ml AN Big Bud
10 ml Liquid Karma
5 ml Sweet

Should give roughly:

N - 106
P - 51
K - 263
Mg- 54
Ca - 32
S - 53
fe - .79

with 3/8 tsp Gypsum, should be roughly:

N - 106
P - 51 <-- P is still low and can't add anything with K as it's already high
k - 263
mg - 54
ca - 137
S - 53
fe - .79

Is there any P boosters that don't add K? Also, why wouldn't the people formulating these mixes catch the low amount of P??

I enetered all the info for AN A+B base nutes so we'll see how they are forumlated...

 

[seek_UP]

Ok, for Advanced A+B bllom nutes (7.5 ml each), Big Bud (10 ml), Liquid Karma (10 ml), and Sweet (5 ml).

I come up with the following:

n - 141
p - 63
k - 276
mg - 58
ca - 34
S - 61
fe - 2.77

with the added gypsum (3/8 tsp):

n - 141
p - 63
k - 276
mg - 58
ca - 139
S - 61
fe - 2.77

Also low in P. Maybe this is for a reason and the mel frank formula is off, don't know but it seems too obvious for the nute manufacturer to miss.

 

[seek_UP]

I have some old technaflora BC nutes that I will plug into the spreadsheet to see if they come out roughly the same. I'm guessing they will.

If anyone has any other base nutes or additives, they should add them in also, we could make a thread with the breakdown of all the popular nutes, this would also make it easier for people to mix nutes/additives of different brands..

One more thing, AN Overdrive doesn't list a guaranteed analysis on the bottle..
I may email drop onto their forums to see if someone has that info.. If anyone here has it, please post.

Looks great! You got the right idea. 63 p is probably plenty. Watch your n being 141 in flower. You should try to get that toward 100. 100 p is alot in the mel frank formula.

How about this:
(all amounts are per/gal)
12 ml PBP bloom
10 ml AN Big Bud
10 ml Liquid Karma
5 ml Sweet

k - 263

For bloom that will work just fine. Your n is lower. Doing great!
