Im running 2 QB 304s and had the same damn calcium deficiency, im thinking i need to turn my lights down in addition to adding calmag... i was running over 240w for a time and im down to aboot 210, prob gonna drop to 190 and see how they do.

Im pretty new at all this so i was affraid to go much above 2 ml per gallon. Theres so much information online i couldnt decide if they had too much or not enough, or too much of something else etc etc etc

Anyone know ppm in veg and flower for MC? My boy using it always tries to make everything more complicated. Thanks.

OP, looking excellent

FYI, I tried HydroHalo drip rings, but fought algae build up clogging them. I even drilled out the holes, and still.. I THINK I was using Hydroponic Research Veg + Bloom at the time

What size pump were you using? Mine was ~ 240 gph, which could have been too small for all the tubing

This forced me to go back to my roots- F & D

Feeding chart on the website.
https://greenleafnutrients.com/feeding-chart/?v=7516fd43adaa#1503551740849-5add0c8a-5261
Enter the amount of gallons you are mixing to the ppm calculator.
There is a suggestion of how many grams to add per gallon for each cycle of the plant from seedling to flower on the site as well.

Enter the grams of nutrient you will mix to a gallon for your stage of plant growth.
Once you have that entered it will give a breakdown of ppm for each element in the nutrient and a rough estimate for total ppm.
(e.g. @ 5 grams per gallon)

No worries on the thread, @kit10 Soil or ? What's your leaf texture like ? relaxed leaf sets could be not enough or too much water at lights out. The girl on the left was stunted only because after it was topped , both mains grew together.

I watered every other day and now water every day. I use MC with every watering "every other day and now every day" and currently at 6 grams a gallon.

Hey ill be running MC this year using ffof I might have missed the answer in this crazy long thread lol but did you start watering every other day using 2g per gallon right off the start? I' just trying to decide how often to water using MC. Plants looked amazing btw!

I did a few grows and im on the fence. I feel like i had better luck with the soil plants than the hydro.

But i had bad humidity issues this year so i cant point the finger solely at MC. But i had nitrogen issues (too much) late in flowering.

stuff is strong. But u need to know how to feed plants properly, because it matter by plant size, and watts used. You dont feed a 1000W plant the same as a 250 watts plant, because they have difference needs.

If you using 250 watts, your PPMs should never be more then 500 PPMs per week in peak flower. I like to use the same ppm as my par. I know it sounds odd, but i think it measures up to each other in the LED world.

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.

That has to be the 700 scale, right? (2.14 EC, and not 3.0 EC, right?).

I would like to say here I wish everyone would stop combining calcium and magnesium as the same issue.

my well water has gone softer with the dry summer and I have calcium issues in my garden. But not magnesium and cal mag products make the problem worse.

The solution is calcinated or agricultural lime. Not dolomite which has way too much mag and also makes my problem worse.

Or for hydro I would want a chelated calcium product.

I also find this is an issue we should take note of. Especially since "CalMag" is also often the given "cure-all" for any type of issue cannabis gardeners run into. Most of them have Cal, Mg, N, and even some other micro nutrients or additives. If all the plant needed was calcium, you could make it worse. Also, it could have been neither of the elements actually causing the issue, but pH or environmental.

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 ?

I used a lil bit of crop in my bubble cloner last time. I used cloner gel dip first, then some MC in the water. Rooted in about the same time as no MC
