my Polar Gelato is starting to show quite pronounced foxtailing, I don't know if it's from stress or genetics... do you think it's concerning foxtailing? I'm on day 64 of flowering out of the declared 63 (you can check the diary)

Is it worrisome foxtailing? Genetic Foxtailing: If it occurs evenly across the entire plant (especially on Sativa/Haze strains), it is completely harmless and natural. No action is needed! Stress-Induced Foxtailing: If it only appears on the top buds closest to the light, it is a response to excessive heat or light intensity. What to do: Check your canopy temperatures and light distance. If the tops are getting baked (above 28°C) or hit with too many photons, dim your fixture by 10% or hang it 5–10 cm higher. When checking trichomes for harvest, look at the main body of the bud, as the new "fox towers" will continuously pump out fresh, clear capitates.
