Bubbleponics - O.K.C.

Notes from 8/9/2024: PH has been slowly dropping by 0.1 a day all week.  Finally turned around this morning.  I had to PH up from 5.5 5.7 yesterday and it was 5.8 today.  I do see tip burn on most leaves so I am suspecting I'm over-feeding now.  I will need to step down to 3/4 strength.  I've added ~ 4 gallons of R/O this week and the EC is at 1.8 1.4.  So it looks like in the 1.4 range the plant is beginning to feed again.  I think 3/4 strength is around 1.5 so that should be just about perfect for next week I hope.   Compared my grow to another guys grow: https://growdiaries.com/diaries/69538-ethos-genetics-orange-kush-cake-grow-journal-by-trichome-threshold/week/384176   That is from his 5th week in bloom.  I'm not sure if he's taking pictures at the end or the beginning.  I'm going to assume the end.  I think he's a bit ahead of me overall.  I did have to play around with the dimmer today, but I doubt the lumens are the issue on why I might be behind. Notes from 8/10/2024: Water Change Day   I went with 3/4 strength of the modified nutes after encountering tip burning symptoms worsening and ph dropping throughout the week:  A: 2.84g  - 15gal - 42.6g B: 1.89g - 15gal - 28.3g C: 0g ph 5.7 EC 1.3   Took pictures
