Is it necessary to add other nutrients to the megacrop? Is that because the base doesn't have the necessary nutes?
You can run MEGA CROP 100% all the way through solo, also you can add in PK Boost (0 Nitrogen) type product during flower time to really customize. There are a few other products you can mess around with also depending on your grow preference, but MC is essential and can be used standalone.
I usually recommend to people to do a few solo MC runs and dialed it in first, then to consider experimenting with a few other supplements just to see if it benefits them.
We must be in parallel universes and at the same point in time. Late in flower using Greenleaf, noticed with a reduction in MC and boosting PK with Bud explosion making a nice difference with the end of flowering. Still learning how to use the MC. Yea its simpler than other nutes, but still find there are things to learn WHich is cool to me. If it was too easy, it would be boring.
yeah, there is definitely a "dialing in" learning curve, which to be honest comes with literally any nutrient system. MEGA CROP will be easier to dial in compared to other products because its 1 simple product, so you are only adjusting for 1 variable which is the easiest thing to do.
Dialing in is requires because of slight differences in strains genetics, whether its autoflower or photosensitive strains, lighting types/conditions, grow conditions/environment, medium, etc... So the Feeding Chart on the website is basically just a suggestion.
So usually the dialing in process is something like determining how much to feed depending on your week in cycle (week 1 veg, week 2 veg ... week 5 flower), but its usually fairly simple. Like you might end up with something like
week 1: 4 grams per gallon
week 2: 4.2 grams per gallon
...
week 5: 5 grams per gallon
week 6: 5.5 grams per gallon
...
So its going to be somewhat relative to the Feeding Schedule, but slight adjustments may need to be made.
