Foxtailing or genetics

The Pr-to-Pfr conversion, triggered by red light exposure, plays a crucial role in floral development, this conversion, where the inactive form of phytochrome (Pr) becomes the active form (Pfr), initiates a cascade of events that ultimately leads to flowering or inhibits it. High levels of Pfr, maintained during the day, suppress flowering. Also known to initiate shade avoidance, high levels of far red outside of sunset will cause plant to think it's under the canopy of a tree or other plant and stretch to get out the deep reds.

is it only happening on the top colas? doesn't mean it still isn't genetically predisposed to it. Might need less stress for it to happen, for example. I'd lean light-related this time... i get knobby buds on a plant or 2 in each grow, and i'm pretty sure it's from me applying slightly too much light at the top. This would be about overall DLI and not from specific wavelengths throughout day. knobby and substantial (dense) is better than spirally, loose foxtailing. if it's weak spirals, i snip them off while trimming. 1 or 2 loose calyxes with excess twig isn't woth it. if it'll break into decent smokeable flower i leave it.

This is such a tough question to look into. Is your varietal something that was bred in the past 5 years? Then it is genetic, otherwise not. With the resurgence of hash-heads being the penultimate kings and queens of the industry once again, folks have been actively chasing foxtailing down and intentfully breeding it into cuts... more surface area, washes better. Makes for garbage flower though IMO.

Uv-a in mornings with 3k kelvin. Uv-b in middle of day with extra blue 5k Kelvin. Uv-a in evening with 3k Kelvin with predominantly deep reds and far reds. Deep red/far red should be applied 30 min as a sunset for the pr pfr conversion. Buds look fat! But can't help notice the deep dark green which is indistinguishable from nitrogen toxicity. I dont really foxtail I see a plant packing on yield with little place left to put it. Too much nitrogen during the flowering stage can lead to unwanted issues such as stretched plants, diminished yields. Enjoy and good luck.

don't know what's causing the foxtailing but the light is a little too intense as evident in the leaf curling...when increasing light intensity if you notice any leaf damage in the process you have gone too far and will effect how the plant exchanges water and air...

Ja kann sehr warscheinlich an der Genetik liegen. Aber es gibt noch andere Faktoren aus lichtstress und Genetik was zur Bildung von Foxzltails führen kann, ich würde auch wieder zu normalen lichteinstellung gehen da sie wie gesagt sehr warscheinlich von der Genetik her so sind
