I’m experiecing a situation very strange and although ive looked a lot for help with long time growers and in a bunch of places i couldnt nailed it.
The situation is that the flower was gorgeous, i mean everything was just perfect until 07/08 when the runoff PH went down to 5.4 (entry 6,3). Since that day, it never came back and the plant started to show the signs of stress and deficiences.
On 07/18 i did a flush to reset and the final runoff was 6.0.
Two days later on 07/20 i gave ferts with PH 6,3 and the runoof was 5.1!! I mean… how is this possible since the soil was suposed to be “empty”.
Today, 2 days later again, i watered with 6,8PH in an attempt to equilibrate things and the PH runoff was 5.0. I have just an idea that there must be some microorganisms, bacterias or etc in the soil and/or the roots activyt that may be resulting in a acidic enviroment. The problem is how to correct.
Strain: Amnesia Haze Auto
Age: 11 weeks
Flowering: 4 weeks.
Ferts: Biobizz and Rapidtsart.
Soil: Inert, Peat + Perlite (70/30)
Pot volume: 10L
Vent in and out OK.
Light: 120W Quantum board.
Grow size: 2x2
I always control the PH and PPM of entry and the runoff.
I was thinking in maybe abort biobizz and change now to mineral nutes that i already have, the entire Remo line, since the absortion will be faster and its easyer to correct some aspects and also considering that the problem might be something related to the microorganisms due to biobizz.
I’ll post the pictures on day 07/08, 07/18 and 07/22
I’ll apreciate a lot if somenone can help with this situation.
My last run was a banana kush auto that end up with 52g.
Thanks a lot.
