Dialing In MEGA CROP for Auto's

[Mañ'O'Green]

Stop. you are treating Light Mix SOIL the same as coco they are not! You need to let the pots dry down to 50% water before you water again.

Then you plain water wait for the dry down, plain water wait for the dry down, Then you fertigate and repeat the 3 period cycle.

1g of Part A in a gallon of distilled water lowered the PH by -1.4 and added 190 PPM
1g of Part B in a gallon of distilled water raised the PH by 0.2 and added 125 PPM

This is from the lot I have your mileage may differ but it is an easy test to replicate. It is simple then to do the math for your PPM target. Remember the NPK calculator on the GreenLeaf website is Elemental PPM and not what your meter measures. Don't mix the two or your plants will be in deep trouble.

2.1*190= 399
0.9*125= 112.5
total~ 512 PPM

I think this might be too much in the Bio-Biz I would drop to 400 PPM.

This keeps the same NPK ratio with lower PPM 1 gallon, 1.7g Part A, 0.7g Part B.

Then go to the calculator on GreenLeaf and enter your inputs 1 gallon 2.1 A, 0.9 B and you get the NPK ratios

8-9-18 NPK That is a good ratio for mid to late flower.

Here is the lower PPMs

Thanks I think that's where i was screwing up. I think my soil got too hot. Cuz I fed nutes every feeding and no waterings in between.

OH YEAH!!!!

Canna Geek stuff!

I finally got a feeding schedule written out and I figured out where I was screwing up. From here on out I shouldn't have any more problems. Water water feed. Repeat. Recharge. Then repeat cycle every week but adjusting feed accordingly depending on week I'm in. So 2 feedings per week instead of feeding nutes every day like I was doing. That's totally where I fudged up. Lil different than hydro for sure but I'm getting it thru my thick stoned head. Bahaha Thanks for being patient with me and helping me yall! Happy Growing!!!

OH YEAH!!!!

Huh? What's that mean? Lol. I just transitioned from hydro to soil so I'm learning shit still about soil growing. Hydro is definitely different. But lots of similarities too. I'm getting it now. Now I'm gonna crush it on future grows and finish this one off nicely too

@Mañ'O'Green do you always use the water - water - feed regiment when in soil? I thought you were a feed every time guy?

 

[WITC]

Does anyone know if I am supposed to feed every watering in pro mix bx? It is a soiless mix so I’ve been feeding every watering. This is the first time I’ve used pro mix. I’ve been feeding at 6.1 and 400 to 500 ppm MC & SC

I just learned feed, water, water. Repeat. But I'm in biobizz light mix. I'm still guessing it's the same. I was getting lockouts due to feeding every time. Read the last 3 to 4 pages of this thread. Man O Green knows his shit. I am a former hydro dwc grower transitioning to soil so I'm learning too. Good luck

@Mañ'O'Green do you always use the water - water - feed regiment when in soil? I thought you were a feed every time guy?

Yes, in soil it is at least water, water, fertigate. repeat. If the plants start to show signs of over feeding add an additional water day in the cycle. I grow in rock wool which is pure hydro so I fertigate always.

You answered your own question - soilless = hydro = fertigate always.

If you see "forest products" or "compost" in your soil mix then it is soil blend and you want to have water only days.

 

[Mañ'O'Green]

Here is a catch 22 on some of these soilless mixes. They add things like worm compost. This makes it closer to a soil than a soilless medium but not quite. The physical properties of compost and clay attract and hold the nutrient ions and release them to the plant via the action of the microbes. Then you end up with a medium that is neither soil or soilless. You just have to watch how the plants respond to your schedule.

Coco vs Peat, Coco releases everything except calcium and needs to be fertigated every time including a little extra calcium. Peat on the other hand even though considered soilless it seems to stay wet longer and hold nutrients longer than coco. So you can have just water days with peat especially if amended with composts.

There is no substitute for experience with the medium and nutrients you use. Keep good notes so you can remember how the plants responded to what you are doing.

I am using Biobizz light. I feel a quart of mega crop water and a quart of plain water per day at this point. I got tiny little pale tips on the leaves but everything else is going swimmingly. Green crack auto 1 m tall lots of side branches in the buds are getting really dense in about 70 days. So What kind of soil is that light mix? I have no idea what the make up is. Also, this is my first grow with a 3 gallon rain science bag. I’m sure that impacts the rate at which the soil dries. Pretty impressive so far
