Red hairs 5 weeks into flowering

[funkervogt]

Hey guys,

I have bagseed which, from the looks of it, is going to be around a 9-10 week job.

Today I noticed a lot of hairs turning red/brown at the tips. I have not changed anything in the environment, but am suffering from potential nitrogen
toxicity/nute burn -> http://www.icmag.com/ic/showthread.php?t=107753

However, there is no mass leaf death or indicators outside of a few burnt tips and rips from being close to the fan. Any ideas why the hairs on all plants are starting to turn red this early?

Thanks!

temps seem likely, just from looks.

have temps gotten hotter?

From the title I was gonna say seeds, but they don't look pregnant to my eye.

No balls on these ladies, I've checked them all head-to-toe.

The temps would have gone down if anything. Also, the places where they would experience heat problems (on their tops near the light) are less-so affected. The lower buds are the ones turning red.

It was very cold last night/today, could that have done it?

cold temps may contribute, I don't really have experience with low temps. This year was the first time I let temps get to like 50f in my room just to see what happened.

I did have an issue with what looked like various deficiencies that was probably only related to the temps.

Didn't notice anything with the pistols though, but I wouldn't rule it out as a possibilty

Im reading from other peoples posts that the temps may very well play a factor in stalling the growth, which appears to be happening. My less contributive plants don't look like their budding much (or producing many trichs) and it's already day 37.

Thanks again man!
