My thoughts on it were to use it at 20%-30% and just increase by 10% weekly. This is on an ebb and flow setup. So using just Mega Crop I was thinking:I think it was me that suggested using the old in veg and the new in flower and that is what I will do this run. I have a two year supply between the two bags 9900g MC1 and 750g MC2.
I will continue to add BE, SC, Kelp Extract and MagPro but I will reduce the amount to half of what I used before. I run a drip to waste so I am running at 80% of chart and It performed very well in the last grow but I think I could have pumped up the colas a bit by reducing the N just a bit. The plants stayed green all the way into harvest. No leaves were drained for their nutes at the end. so that is why I think I need a little less N.
As to the white bits. We mix such small amounts that an out of balance condition could happen but it will only be for that mixing. The next mix may be a little over and the plants will get what they need over time. This is indeed the reason I will continue with the additives that are weighed out separately. There is little risk of the nutrients to be so far off that you would get a lock out situation as long as PH is in range.
I cannot believe there is a stoner in here growing weed that does not own a gram scale . I measure out in grams.
I have a unique situation with my water that requires checking the PH every-time. I am on municipal water and the city has both wells and surface water sources. I live right in the middle of the two supplies so some days I am getting well water and other days surface water. The PH and PPMs is different between the two of them. I have a 35 gallon top-off tank that I fill and aerate over night then test to see what I have in the tank. I PH it to 6.1. From there It goes into the 10 gallon reservoir to be mixed with nutes and given a final PH.
I do not know If you have seen the numbers but I did a complete 6 plant grow with GreenLeaf Nutrients for $15.30. The yield was 30 ounces cured. The same size 6 plant grow with House & Garden was over $200.00 yield was about the same except I had a bad plant (genetic problem). Now that is real value and the other Nutrient Companies should be shaking in their boots.
Thank You @Greenleaf Nutrients
I run Coco and I measure EC, which is Universal. PPM is not. I honestly only feed lower than full strength during the first few days I feed them. After that it is Full Strength. I use a lot of Cal-mag 2.0g per gal and some Sweet Candy at 1g per gal. I use about 4.5g per gal of MC. This total mix comes to 1.1-1.2 EC. So he is probably right with about 500ppm of just MC if you were to measure it.So what EC would you shooting in veg? or flower? I remember @pops22 was at something like ~500ppm , and I assume that was late veg or flower.
I think your starting point is too low and end too high for an ebb and flow. I would start 40% and end 80%. Unless your table floods over the top of your rock wool you are going to have a salt build-up problem just above the water line. To combat this top water every couple of weeks.My thoughts on it were to use it at 20%-30% and just increase by 10% weekly. This is on an ebb and flow setup. So using just Mega Crop I was thinking:
6grams / gal
20 Gal tank
20% 24g Week 1
30% 36g Week 2 etc.....
For those of you that have used this product or not. Does this seem like its solid and will result in the least amount of risk/success?
Unless Greenleaf assures us from results of actual product life-time testing done with diluted MC, I doubt a product formulated to be stable as a dry powder will have long-term stability (weeks, months, longer?) as a concentrated solution. Chelation and sensitive nutes will presumably decay faster in water, particularly when the product lacks additives or otherwise is not stabilized for long-term dilution.........Btw, I am thinking about making a concentrated liquid out of the whole sample bag.
