Leaf tips dry-yellow. Overfeeding? Not enough air?

Hi all
I got this Jamaican sis into a pc box. Her leaves have dry and yellow tips.
There are no fans yet in the pc case and I use about half of the nutrient solution dose.

Is she yellow because of overfeeding?

i say that ur leaves look burn but not sure ask riddleme lol

Yes they do look burned. What shall I do though?

i have the same problem which i understand cause i have been feeding my plant nutes till the tips burn it just today it started burning again since i up the dosage but all is well wont water for 2 days day and a half let it absorb all the nutes and water before i give it some more.

And my friend if nute burn is your problem and it doesnt get any worse then lower the dose a little till you see the tips turn yellow just to let you know thats the max nutes it can absorb before hurting. At least thats my way and theory
