Dialing In MEGA CROP for Auto's

[NorthernLights_420]

My next tent I am going to design will be a 4x4'x80" tent with 4 autocobs from cobshop.net running mega crop A and B. And I want to do 3 gallon pots and 8 autos in that tent. I'll save my tent that I'm growing in now for 4 photos. I'm from Michigan USA where its legal to grow 12 plants. We have the most lenient law of all the states when it comes to plant count per house. Most states are only like 6 plants so were lucky here.

And that's why I use megacrop, simplicity. I grow KIS style. Its why I never grew bottle fed plants either. It's bad enough I have to use RO with Cal/mag for organic grows and PH it, my water just sucks for canna.. So I figured MC was not much more of an effort. Now I'm getting ready to split my grows between organic and MC. I've got 2 Pineapple poison in organic soil right now. But I'll still grow with MC also!

Yeah I was thinking a week or 2 old before I started feeding her. 7 to 10 days above ground sounds fair too. I dont have a ppm meter though. I had a nice bluelab all in one meter when I grew hydro but sold it when I sold my old set up when my lung collapsed and I couldn't do hydro mo more due to heavy lifting water buckets. I'm going based off of grams per 1 gallon. Mixing in a 1 gallon water jug. Recommended feeding is 1.5 grams per gallon of part a and 2.5 grams part b. So maybe I'll scale it back a half gram on each and see how it goes some time between day 7 and 10. I've always been a fan of under feeding verses overfeeding. You can always add more but you cant take it back in soil. Hydro is easy to take it back. Just redo the whole res if needed. But soil you cant change the res. Even in hydro I felt less was more. I never ran over 650 ppm but usually I kept it between 500 and 600ppm during flower and dropped it as they got closer. I used to fuck with too many bottles of shit. Why I chose megs crop for simplicity. I used to add 4 gallons of 0ppm RO water. Then I'd add 50 ppm of armor si. Then 150ppm of cali magic. Then base nutes By GH-micro grow and bloom. Then liquid kool bloom and then ph the res. Then let everything mix good and then I'd add hydroguard. lol. The way I'm growing now is so much easier to tend to. Mix nutes in water. Feed and go live your life and check on em once a day or every other day. Good to go. Lol I like keeping it simple. I thought my system was easy before. Man this is a cake walk. Lol

My plants just popped above ground a few days ago. There still babies. How many weeks into the grow or how many nodes before you give your first feeding? 500ppm sounds like a lot of nutrients for a baby plant.

That's total ppm. I tested my water first and went from there.
Day 14 for the oldest

Got it! Cancelled the BE on my order!

 

[NorthernLights_420]

pops22 told me 500ppm total for young plants. My young ones have surely responded. with one feeding last week and due for another in the next couple of days when soil moisture declines a little. This is from Friday morningat day 19 Gelato 33 from Linda seeds in a 7gal pot. She has grown over an inch since then.

Do you adjust ph or not? If so what do you use? Is general hydroponics ph up and down safe to use or? I've read some ppl say they dont ph and others say I shud ph. New to soil and mega crop. Used to grow dwc hydro.

 

[NorthernLights_420]

Can anyone else chime in on whether or not you adjust ph? And how do you adjust if so? Just general hydroponics ph up or down or?

 

[pop22]

Yes I have to PH, my water is nuts even after RO processing it's often alkaline. One PH up or down solution is as good as another. And people who say they don't, well... sooner or later it will bite them on the ass! When you grow in containers, you should PH your water and/or solution always. Outdoors it doesn't matter as the soil has lots of buffering capacity I run my MC at PH 6.4 to 6.5. That has worked very well for my. I have a photoperiod right now, at about day 116, never has had so much as a spot on a leaf!

You don't have to pH MegaCrop (but you can't go wrong and probably should). A good number (I have done and am currently doing this myself) have reported doing well without adjusting pH (but presumably starting with good water). MegaCrop is rather adaptable and apparently works well over a wider range of pH compared to many other base nutes, whether due to it being self-buffered or having better, more bioavailable nutrients, such as better chelated forms.

If base nutes, whether MegaCrop or AN pH Perfect, work well (with your water) in terms of actually growing the plants without need for pH adjustment, why add more salts to adjust pH?

 

[NorthernLights_420]

Yeah I've seen mixed reviews on this. Confuses me. Lol some say ya and some say no.

 

[pop22]

Sure you can not ph, you can ride a motorcycle without a helmet too! Until you crash.........
