Howdy Folks,
I wanted to see if the community would be able to offer some guidance with an issue that I've been having. Here's my set up:
2 Plant site 3 bucket RDWC, res is external to tent. Total working capacity of the system is about 16 gallons.
Tons of air
400 gph inline pump
260w HLG RSPEC light
General hydroponics nutes using LUCAS formula (1 part micro to 2 parts bloom)
2 ml gallon calmag
2 ml gallon hydroguard
RO water starting at 0 ppm.
Res changes every week
growing Tropicanna banana
44 days into flower
Ph is being monitored by bluelab Guardian ph monitor
A typical reading will look like this: 510 ppm, 71 deg, 5.8 Ph
The problem that i have been having, is that every week when i do the res change, the ph will drop considerably the day following the res change when the lights come on.
For example, i will change the res at about 6pm the night before (lights are on 11am to 11pm) and ph to 5.8. The ph will be fine all night, even until the following morning where it may drop as low as 5.6-5.7. When i check it when i get home from work (around 5pm) the ph will have dropped down to 5.1. I adjust with Ph up to 5.8, it will drop once more to maybe 5.5-5.6 over the following day. Then it is usually good for the rest of the week.
When the Ph is dropping, the PPM remains about the same, may hover up or down about 10 ppm. Water is being consumed about 1.5-2 gallons per day.
Would really love some help in diagnosing this issue. The plants don't seem to exhibit issues indicating any deficiencies or toxicities.
Thank you for anyone who took the time to read this and offer some advice.
