Those white cotton buds are light bleaching.Surely. Examples of cotton top can be seen here:
Sorry for the camera white balance problem in the first pic. All but one of these was turned around (CT eliminated) by increasing nute delivery.
Also, your tip burn may be a function of the root's exposure to the nutes. Coco has the slightest bit of retention. Have you tried flushing and if so, did the tip burn stop? All of this aside, if you are happy with what you are doing and the medicine is good for you, that's all that matters.
Too much light.
Yours is foctailing caused by excess heat.Interesting! I am pretty happy so far - it is my first grow, so I am sure that could be doing a lot of things better/smarter. But the girls are alive, and within a week or so of finishing. The end is in sight!
I did start to see some foxtailing on one gal - a Green Crack photoperiod. I don't think it is stress related, as the other girls are all fine. Temps and RH are in the zone, and no light-leaks. So I (and a couple of other guys here on 420 who are much more experienced than I am) am thinking that it is just "natural" foxtailing. The last variable I could think of is the red light, but you have alleviated that concern as well. Here's a pic, just for reference...
Thank you again.
