I have been growing for a few years, exclusively with ILGM seeds. About 16 months ago I began growing hydroponically. It was a smashing success right up until week 5 of flowering. Within about a day and a half, the plant just straight died. Suffocated by the pythium that had coated the roots completely. I less than a week, the remaining 3 which were dirt grows in flowering died, as well as the four I had in a separate veg booth (1 hydro / 3 dirt). All from extremely aggressive pythium. I mean, within hours of the first sign the plants began drooping. My whole operation failed for the first time. Since then I haven’t had a single plant make it to successful harvest. I completely sterilized all my gear. Bought new stuff when necessary/possible. Started over. Every single plant now begins to show the telltale amber roots of pythium infection within a month from seed. I monitor conditions like an autist. Temps have NEVER gone outside the nominal range for neither: the booth ambient temp, the surface temp of the plant, nor the reservoir temp. I’ve even tried using different nutes, EVEN JUST STRAIGHT WATER. ( I only use RO water). The reservoirs are all completely UV proofed.
I’m pulling my hair out over this. I’ve spent over a year trying to get this sorted. I’ve lost dozens of plants.
This has driven me to a place of throwing my hands up and just giving up.
Does anyone have any ideas? I’m open to everything at this point.
