Hempy Headquarters

Thanks. About four tubes per square foot, maybe five?

I would say 4 is a good starting point for running estimations.

I have included an attachment that show the first two I have harvested.

As you can see from the pictures I included dry/finished weight to the scenario. I was not happy with the growth pattern on the back pheno but I did have a rooted clone before I knew what she had to offer. The front shorty had some weird self topping thing happen half way through flower. I did want to mention that these two that I have put into jars did have some issues I think hinder this rounds numbers. But with all that said I believe its safe to say that the remaining tubes will yield more than the first 2.
 
Here is a Grape Pupil that I have in veg. Pure perlite hempy using megacrop. This is one of 2 plants I have started using megacrop on and has looked great. I am at around 4 grams per gallon.

First time with any issues with megacrop. I am trying to dial it in cause I really like it. Any Ideas on this?
Haven’t used MC, but I’m pretty familiar with VegBloom (single part dry nutes like MC). They also recommend 4-5 g/ gal but on one of my current plants I ran waaaaaaaaaay under that amount and saw much healthier plants. I can measure on a digi scale tomorrow to give you more accurate data, but you could try a lighter feed and see how that does you.
 
I am using Mega Crop 1.0 and as a rule have found 6.2 - 6.5 grams per gallon to work very well for virtually all plants I've run. Once in awhile a plant will need more Cal-Mag then the 1.0 can give it.
 
I bumped the dose up from 5g to 6g/gal (V1) on April 26, because she was showing some early fade on lower leaves. Now, she’s doing the claw, so I cut way back to 4g last watering. Sheesh! :rolleyes:

Edited to add that I also add 3ml/gal CALiMAGic.

Interestingly enough I’ve seen a lot of calcium issues under LED and so what I did on this current grow was drop my VegBloom (base) way down and supplemented calmag plus with Age Old Calcium Carbonate (20%) and a sprinkle of sea salt. Plants were crazy healthy in veg, but calcium is a tough nut to crack because the stuff I want (carbonate) is super super alkaline and drives pH way up. Additionally it mixes with water about as well as... cement. I’m looking into a cal from Biomin that’s supposedly more water soluble, but only comes in a 5 gal bucket.

Edit: idk if you grow under LED, but I do and noticed issues for sure.

I asked my original question to see what other MC users were doing and intentionally left out some info for the fact that I had some of my own assumptions and wanted other views and points.

I do grow under LED and I when I started adding CalMag to the mix is when my issues started. My assumption were I need magnesium only. I don't have a single source magnesium additive like epson salts so I used what I had. I was told by a rep at greenleaf to add more MC as he felt like my 3 or 4 grams a gallon was a little light. I did what he suggested and the problems went the way of the buffalo.

I was very impressed with how much the plants love what's in MegaCrop and wanted a way to correct the magnesium deficiency if one was to occur. The "Sweet Candy" has 5.5% magnesium along with potassium and sulfur. This was my way of supplementing for growing under LEDs. I have been at 6gr of MC and 1gr of SC for the last 10 days and the plants are growing like weeds.

As of writing this I received some 250gr of the "Bud Explosion" from greenleaf nutrients. I haven't decided what to do with it yet. As much as I like the idea of feeding a plant for every stage of growth, I wanted to watch what MC can do on it's own. What do you guy think? Should I keep with the MC/SC or should I add the bloom boosters?

Haven’t used BE and so can’t give any relevant opinion (sorry man). Magnesium deficiency does seem a bit odd with 4/gal + calmag, but your leaves give off that look so it’s hard to say. I sort of lucked out because one of my bell pepper plants started having blossom end rot which helped me figure out my issue was calcium...

I’ll be watching whatever you do as I’m curious to learn and hopefully help figure it out with ya if there’s anything I see that’s not a guess.
 
Just be careful, that BE is some very powerful stuff!
:oops:
I was thinking a pinch at the most. Like a baker.

For sure. Please post any relevant info that you come up with. I am hoping to dial in the greenleaf offerings as they respect my wallet more than most nutrient companies.
 
I've been running 1tsp Mega-Crop (v2) per gallon. No additives aside from white vinegar for ph down.

I used to use Maxibloom as a stand alone. by using Mega-Crop by itself from seedling to the end of stretch and then going to Mega-Crop and Maxibloom at 1/2tsp each after stretch I have noticeably increased yield and overall quality.
 
I see that Greenleaf has changed the Bud Explosion formulation since I entered the guaranteed analysis into my spreadsheet (used to be 0-23-44).

It is now 0-19-39, which provides 22ppm P and 85ppm K. :rolleyes:

Sorry for the error.

The more I thought about this last night I agree the issue is (Edit: way more likely) the bloom enhancer (than magnesium deficiency). I didn’t realize Bud Explosion was MegaCrops bloom formula.

I haven’t run megacrop, but very familiar with VegBloom and their equivalent of Bud Explosion is called Shine (way lower PK concentration than BE so I get Felipe’s comment now).

Friends and I have had good success with the ratio, if Felipe can help out with some backwards math it could be a good ratio to try.

VegBloom: 8-5-13 @ 4 grams/ gal
Shine: 0-22-12 @ 1 grams/ gal
 
It’s a pretty simple formula that I have built a spreadsheet around:

Nute% x Dose (ml or g) x 2.64
(x w/v for liquid)

Straightforward for dry fertilizer. If liquid, you have to multiply by the density for more accuracy. And you have to multiply the result for P by 0.43, and by 0.83 for K.

For example:

23%P (dry) x 1g x 2.64 = 60ppm x (0.43)
= 26ppm

If liquid (say 1250g in 946ml - from label), you would multiply the above by
1250/946 = 1.32 x 26ppm = 34ppm

Let me know if you have any questions.

So what would the equivalent dosage of MC/BE be to (4g/g VB + 1g/g Shine)? Not being lazy, I’ll just fuck it up so I’d rather have someone who understands the logic and will get it right provide the info. If you have a formulation for EC I’d definitely be interested in that, I don’t go by PPM due to varying nutrient scales. Gets too confusing for me to track.
