I'm in a lot of pain currently and high as fuck, so I don't know how much sense this is going to make...but I'll give it a shot.
I keep It pretty simple, a ratio of 3-2-1.
In veg it's:
3 parts grow
2 parts micro
1 part bloom
I start rooted clones at ~500ppm and work up to ~1000ppm by week 5
When I flip to flower I'll give them 1 week of equal parts at 1100ppm-1200ppm.
After week 1, it's back to 3-2-1 but it's switched to
3 parts bloom
2 parts micro
1 part grow
There are some times in flower I'll notice my plants are a little heavy with N, I'll usually cut the grow and go 4-2-0.5 or even cut it all together and go 4-2-0
Also when mixing food I always mix in micro first, the rest doesn't matter.
I'll try and break it down a bit
Veg
Week 1: ~500ppm
Week 2: ~600ppm
Week 3: ~700ppm
Week 4: ~850ppm
Week 5: ~1000ppm
Flower:
Week 1: *Equal parts food* @ ~1100ppm
Week 2: 1200ppm
Week 3: 1400ppm
Week 4: 1500ppm
Week 5-8: 1600ppm, and at this point, depending on how things are looking I may increase my food to 1700-1800 or even reduce it back down to 1500ppm
Weeks 9-10: I'll usually give the plants a 10 day flush, replacing the res every day with fresh clean water....depending on what's going on in life at the time, it may be more, it may be less.
Edit, I don't know what conversion rate my PPM pen uses but this is the one I have.
