Eventhough I hate the new Growdiaries Design here is another Diary.
This is my second run with Mephisto Genetics Ultra G13.
I was stoked with the results of my first grow with it and now want to test something new.
I stalked the 420autoflower method and am trying to copy some aspects of it but not all.
The Fertilizers will stay the same as usual but the rockwool stacking style I did copy, not sure yet about the super cropping aspect.
The seed germinated as usual, so far 100% rate overall with 3 seeds from Mephisto.
Sprout ~21:00 on 22.01.2025, counted as day 1.
The seedling was really really light hungry! I started with 300 PPFD and it stretched and stretched until I increased it to 500 PPFD mid week.
The seedling is growing good and the fact that it is so light hungry gives me a good feeling :)
Values are average of the day.

Plant is doing fine, like its predecessor it is a self spinning plant growth rate is also very similar to the one before, just a little bit slower but not much.
The plant is really light hungry, stretched a lot until about 500 PPFD at the start of week 2, did not expect that.
Will probably top mid next week to have 8 branches total to train.
Increased EC over the week, planning to reach ~1.7 by the end of next week in slow steps.
