Hi everyone! i'm new to the forums and i'm on my first grow from bagseed.
My setup:
Lighthouse growtent 1.2m x 1.2m x 2m
PLANTiT DWC Aeros IV -> 4 20L buckets + central 20L resevoir
Budmaster G.O.D 4 LED light
RAM air blower with carbon filter attached.
(No fan for air movement, though I need to get one.)
What i've noticed now that my 3 plants have started flowering is a few days after a complete reservoir change that the pH of the water drops fairly quickly.
Using the GHE trio of nutrients; FloraMicro, FloraGro and FloraBloom.
For 45-47L of water I add 62ml Micro, 31ml Gro and 91ml Bloom.
When I do a complete water change, I'm adjusting the pH after adding nutrients down to 6.5.
Before putting my plants back in their buckets, I wash the pebbles clean with 15L of clean tapwater per plant.
All done, pH in the reservoirs is around 6.5.
I check the pH every day and I'm noticing that it drops by about 0.2 - 0.3 every day.
4 to 6 days after the change the pH around the roots will be 5.5 ish, and can drop even further to 5.1 by day 7-8.
Observations:
Roots of all 3 plants are colored brownish, but not slimy at all.
Roots seem to be tangled together,
Have seen new white root growth.
Plants themselves look happy enough, though some older leaves develop small brown spots on them.
Temperature is around 75F,
Humidity varies between 53% - 65% during the day.
My biggest question is: why does the pH drop so fast after a water change?
Will post pictures of roots & plants on next water change.
Thanks
