Foxtailing From Heat Stress

[justicebzwieg]

Foxtails, those odd towers of calyxes growing out of the top of a bud, are almost always a sign the canopy got too hot or the light was too close. Autos under powerful LEDs in a small tent are especially prone because the plant cannot be moved further away without losing height. The photos comparing genetic foxtailing to heat induced foxtailing on https://turboautoflowerseeds.com helped me stop blaming the seeds. Dropping the light intensity by a third fixed it for me.
