Are you sure it's low iron and not just lime-green centers from rapid growth? My plants are growing fast and they are all like that. 6 different strains. Takes a day or so for the chlorophyll to green up but it's a good sign and has nothing to do with iron.
both the new & old versions of megacrop i cut in half with epsom salt into upon arrival. mc is great but a local store near me was closing after 90 years of service & i bought enough jacks citrus to last quite awhile, so i wont be picking up anytime in the near future.
I can assure you, you wont be dissapointed in the mega crop, the green terra additives are a real bonus tho, honestly no need to buy any nutes for a while. I have a fuckload of this stucff now lol.I just received a Mega Crop prize from @AquaTerra.
2kg of Mega Crop 2.0
1kg of Big Up 0-52-34 for early flower
1kg of Rock Steady 0-0-62 for late bloom
1kg of Carbo. Pure dextrose as far as I can tell. Tastes pretty sweet.
Going to use it on a couple of currently growing plants to see what happens but once I have some clones from the same mother in a couple weeks will do a little side-by-side with my usual AN nutes. Will be growing in ProMix HP that has a bit of composted manures, EWC and myco added.
I'm really impressed with all the goodies in the MC and printed out their flyer.
N,P and K are all 1% higher than MC 1.0
Mg up 0.1% from 2.3 - 2.4
S up 0.2% from 1.9 - 2.1
Everything else is the same.
You can print this full page greyscale and it's clear and easy to read. Colour if you want but I only have a monotone laser printer.

I ran their calculator for 10L as that's a common measure for me to go by.
Grams per 10L PPM .5
Seedling/small plant 5.29 227
Normal Veg 10.58 555
Long Veg 11.90 625
Bloom Wk 1-2 13.23 695
Week 3-4 14.55 765
Wk5-Harvest 15.87 835

They give away a 300g sample. Link at the top of their pages.
The NPK ratio of 10-7-18 is backwards to what I would normally want in veg at least but seems right for flower so I guess I'll find out how it works soon enough.
Never too old to try new things! Especially when they're free!
Will be nice.
Firstly,I am one of the belief that Cal-mag isn't the end all be all cure for mj plant issues, yet it has been hammered into our mj subconscious to "slap some cal-mag in their that'll fix it!"
Planning to. I've experimented with a lot of different nutes the last 20 years but AN has been my main one from 2001. Wasn't happy to see the pH Perfect come in at the time and didn't get any until it had been out for about 6 years or so but really like it now for ease of use. Never having to bother with pH is a blessing.
I am using hp promix soiless substrate, pH is good at 6.2, i have 4 different cultivers going right now under 600watt MH in a 4x4x6' grow tent for veg. Purple kush, blue cookies, Bubba Kush and Chem dawg..but only the bluoe ookiesare having the issue..I will post some pics when I get home. I am a grower at one of the largest LPs in the world and haven't aeen this issue before..
They making any money yet? They'll never make a dime off of me but then I haven't had to buy pot for over 30 years so not starting now.
Cool.Appears you have a finicky cultivar...the outlier.Everyone else getting the same feed are doing fine.
Agreed.If your nute regimen has all the goodies a plant needs and something is still amiss and the girls are unhappy,check other parameters before adjusting or should I say adding more nutes.
Are you sure it's low iron and not just lime-green centers from rapid growth? My plants are growing fast and they are all like that. 6 different strains. Takes a day or so for the chlorophyll to green up but it's a good sign and has nothing to do with iron.
We made 46 mil last quarter, and I totally agree with you. Why buy when you can grow your own the way YOU WANT and strains that you choose. Way more worth it in the end. When you buy you don't know what kind of issues the grower had.. deficiency to disease..from environment stresses to pests. Those are all variables you can contact your way, what you think it best. So why not grow your own?!They making any money yet? They'll never make a dime off of me but then I haven't had to buy pot for over 30 years so not starting now.
Yeah I been a home grower as well for 15 years, my first thought was PH, looks like it has some nutrient lock out maybe. Especially since the other cultivers arent experiencing the same issue. And yes cal mag is actually recommended for iron issues. But I tested PH it's been steady between 5.9-6.2 for past bit. Because I was going to try a quick flush but decided not to after triple checking PH. I also thought it could maybe be some heat stress or light burn but again only the Blue Cookies is suffering. As you can see In the pictures I am adding below, so it can't be that either. That's why I am thinking this particular strain has iron deficiency
What EC are you feeding at?
Yeah, that was exactly my first thought was ahh PH is facked!!!! But after testing 3 times and getting 6.1 for PH I was like couldn't be PH. Maybe my digital PH Tester is broken or needs a recalibration. I am going to try the old litmus paper tonight and see what it has to say. But I think it looks like nutrient lock out personally..That does look nasty and the way the newest leaves are distorting looks like more than just iron not getting up there. Generally that's a pH issue causing multiple micro-nutrient lockout. Decent calmag has iron in it like the one I have. I don't recall ever having an iron issue on it's own the last 20 years but the memory ain't what it used to be either.
I'd water it with pH 5 and knock the pH down a bit as it's generally high pH that causes lockouts like that.
Could be a genetic quirk too but most likely pH.
