The number of days is from the flip to 12/12. I am not using the calendar to determine harvest. I am using the numbers for future reference so I have hard numbers to know when certain changes were made. I am hoping that after a few grows, I start to get my record keeping dialed in a little better than the chicken scratch I have done for this grow. I assume as that falls I to line, it will become easier to get the environment dialed in as well.
Edited to add: going back through the journal, it appears that day 5 after the flip there were flowers starting to appear. Day 10 after flip, she was covered in flowers. I didn't really ever use grow nutes. She is in a mixture of FFHF and FFOF and that was her feed up until the start of week 3 after flip. Last night I gave her 3 quarts of 1.5EC feed until runoff. Tonight I will water in a little Epsom salt and see how she reacts. The bloom food is 1-4-5 so there is some N, just not a lot.
