    Doing a test run of sorts. Testing both Mega Crop and also first time running a soilless mix. Ive been running GH Maxi with adds in FFOF.

    about a week or so later after getting Mega 2g per gallon. It mixes better than maxi and is PH stable.

    The latest, they took transplanting well and are starting to take off, they were toped and I increased the wattage to 100W. I'm seeing some yellowing spots on the leaves and will adjust the res PH to 6.3

    Not much of an update pic wise, moving to 4g per gallon as the plants start to take off. The PPMs have been high compared to what I'm used to. Mixed 2 gal in the res with 8g MC, water PPM 75 and mixed getting 1500 PPM - 75 = 1425 PPM. @GreenleafNutrients mentioned to me to follow the gram per gallon through the stages.

    I can see a jump in growth with the first week of watering with MC. Its a lot cleaner in the res too vs Maxiibloom/grow. Bumped it up to the suggested 4g per gallon for the rest of the veg stage and then ill drop the scrog.

    Just for clarification, the first picture of the newly transplants to the state you see them in above is 8 days. The goal of this test is to try out soilless vs soil to see if I can fill out the scrog faster.

    by the way, the ppm measurement on your meter will include the NPK and elemental nutrients, and also all the additives and supplements, like the kelp, aminos, etc... So, usually you should base PPM off elemental nutrients only, since plants uptake those as required. So in other words, the ppm will run a little high because of the other additives.

    Thank you for responding to this as I wanted people who follow this grow to read your explanation you stated to me in a PM. I'm not going to dilute and run as prescribed, my plants seem to be loving it.

    I think I was the first person on RIU to do a complete run with Mega-Crop. I had amazing results. Ph was really stable. One of the first things I noticed about it. And I didn't have one burnt tip on the entire grow. 2 plants. One topped multiple times. And one mainlined. Same strain. Pineapple Express V2 got 366 grams dried. Great taste. No chemical taste from the nutes. And I only flushed for 4 days. I won't use anything but MC from now on.

    Your grow looks great. I'm subbed.

    Put the scrog in place. Plants look great, I had a PH issue before I started with the Mega Crop but
    things are looking good. The plant on the left seems to be very squat, both plants only topped once.
    I want to see if running in a coco mix will help veg out and fill the scrog faster. My first time running a coco mix.
    My watering system isn't really a hydro system, its more of a self watering system. I normally run FFOF soil. If I want to go away for a few days I can and not worry about the watering schedule. Also all the lines and fittings are clamped. Fell free to ask questions or leave remarks.

    My last feeding with Mega-Crop on my pev2 was like 1780ppm. Reading that way.

    The plants with Mega Crop are absolutely lush with growth. I haven't seen any nutrient and I've tried all the top brands do this. The growth and health is amazing and I like what I'm seeing so far.

    @GreenleafNutrients has anyone tried to use a small amount of MC as a cloning solution ? Or do you have anything for that area ?

    hi Chaos, yes you can use it for cloning solution! It has some natural cytokins and hormones from the kelp extract that can stimulate root growth. I would recommend using the Feeding Chart,
    Use Veg 1 schedule, and then you can cut it in 1/4th or 1/2 for cloning.

    whytewidow Well-Known Member

    I used it to clone with also. Mega-Crop is awesome. I'm running it on my 90's Purps cross and some testers for mass medical.

    Curious, when you say PH stable, do you mean you get your desired 5.8-6.whatever without adjusting with PH up or down? Plants look great!

    ChaosHunter Well-Known Member

    Yes I'm hitting 5.8 with my tap water and it doesn't swing way out from day to day like everything else I've used.. I believe it is buffered. I have been using armorSi to bring it up to 6.3 for my mix.

    GreenleafNutrients Well-Known Member Rollitup Advertiser

    Usually for pH instructions, recommended to first mix the nutrients and add all the nutrients (stir it well and let it settle for a few minutes to even out). Then, adjust the pH manually to your desired level (suggested 5.8-6.2 but you can use whatever you prefer). The pH should then stay steady for the life of the reservoir.

    So it really depends on your input water supply, if you need PH adjustment or not. I was using tap water in San Diego which is like almost 9 pH out of tap, so I would have to add pH Down initially when mixing up the batch.

    ChaosHunter Well-Known Member

    I'm going to dial back the amounts recommended as I like to feed small amounts every watering. With the recommended amounts I'm getting amazing growth but my plants are staying squat like bonsai. I need the stretch to fill the scrog and one of my plants is just sitting lol. I am thinking of cutting the amounts in half at least for Veg with my setup.

    Mega Crop is some serious JuJu ! The only nutrient that would override my tap water buffer and hold it close to my adjusted PH is Advanced PH perfect.

    Small update and you can tell from the last pictures there has been a lot of growth. Its been a wild ride for sure and growing with a coco mix is very different than soil.
    You cant really over water but you can water too often ! I believe that is why the plant on the left is stunted. Also getting massive fan leaves.

    Note to self: don't use a moisture meter for soil to determine moisture levels. PH closer to 6.3 than 5.8 starting out.

    Mega Crop has been awesome!

    Small update, have been running 4g per gallon and the plants look great, no burnt tips !
    Two completely different phenos and because of this its not key to fill the scrog correctly.
    I could remove the smaller one and just fill with the one with legs. I might just flower them as they are since this is just a test run with coco mix and Mega Crop.
    I have better genetics on deck that I would prefer to maximize.
