Final Bloom, Day 43
It would have been remarkably lucky to have correctly guessed the correct MC level after scaling back from 6g, and I have purposely gone low so as to speed up the recovery and see if I could see what happens when you hit the lower limit. On this watering cycle, we now see what the lower limit looks like... a calcium deficiency. Here it is, classic spotting in the upper third of the plant. I also notice today a less healthy and lighter green in some of the plant, and the angle of some of the leaves has changed to a downward tilt. They need more MC.
Working with MC has been fun, but it also has been a lesson in watching the plants and reading what they are doing, knowing that things can change with each watering cycle. The way I have this timed, when it is time to water every other day, I have the chance to look over the plants and access how they did on the last watering, and adjust when needed. Throughout this entire grow I have been adjusting the MC based on the plant, ignoring the recommendations on the feeding calculator and it is this constant interaction that seems to be necessary. If you think about it, all the nutrient lines have you adjusting their mix a bit depending on the stage the plant is in, but usually you have to go by a chart or spreadsheet or the advice of another grower to find out how best to do it. A megacrop grow is more interactive, more seat of your pants sort of gardening, and the system seems to be designed to talk to you when you need to make an adjustment. It's not pretty sometimes, but it isn't organic growing either... it is you playing the part of mother nature, using the tools provided. MC is a good system and I am starting to like it a lot, but it certainly isn't plug and play. It is imperative to learn your plants if you wish to push the limits.
Today, being an even numbered calendar day, it is watering day, and they got 5g/g MC. They also got their normal dosage of 1g each of SC and BE. I am confident that we have found the correct level, for now... but I still plan on cutting back again... a bit, in this upcoming last week. Lets see if this problem progresses first. Right now it is only showing on one side branch of one plant.
Other than this slight adjustment, they seem to be growing daily, with noticeable bud building going on as these buds work on gaining twice this current size and weight.
