Not sure what's wrong

Hello, this is my first post and also my first grow.

Nice to meet you all

About a week ago, the tips of all my leaves started to curl under, I diagnosed this as an N overdose and I stopped with the feeding, I am feeding it half doses of 4/4.5/8

The last two days I have noticed a burn in one of the middle of the tips of my fan leaves, as it was further than other leaves that didn't show this sign, I discarded the fact that it was heat stress and just passed it on as another symptom of my N overfert.

Today however it started to get worse and has similar symptoms on the outer edges of another blade. I thought I may have a problem with Ph and bought a measure, It was reading between 6 and seven, with 1 in 8 or so readings was reading 5.5-6

Also, some of my upper leaves are curling under from the edges of the leaf (if that makes sense)

I am growing in a 1 galleon pot, and my plant is not rootbound. I have 3 cfl's, 2 11w and a desklamp one which they seem to love and bend towards more than my other two. I only just today installed my fan, but temperatures in my box never seem to go above 30celisius

Also, when under light, the burns look yellow, but when I take the plant out, they look grey :S

I just repotted using soil from my chicken pen which I thought would be full of shit and other nutrients, not sure if this has anything to do with my problem.

Sorry for such an essay, and perhaps its not much to worry about and I'm just being over precautious

Thanks in advanced!

Please help me

Well one is for sure, the plants arent happy with something! Well it can be a few things, first Id say there could be something in the soil, when you say the ph is ok. Also, did you flush the soil?? Soils properties hold N longer then youd think, you cant just expect to water and think the plant used up all its Nutes in the soil. No the soil would store enough nutrients for a week or two. So Id say you should flush your soil, well actually now you repotted, which made a little worry in me, how clean is that soil from the hen pen? some fungi and bacteria that come from dirt, also were birds were is deadly for plants! Lets hope the soil is a little "clean" how long has it been since youve repotted? To see a new sign of life expectr to see the dfifference first in a few days. Also your plant may not be root bound, but a lot of new people like to overwater or underwater, before you water always wait until the top 2-4 cm of top soil are fairly dry, to me it could look like your roots may be rotting or your plants look drowned, could have been something locked the nutrients out, make sure to read up on what kind of nutes you mix and feed together. Sorry theres so much just trying to cover your bases. Sorry bout sloppy english text. I come out of the netherlands. Peace ALSO when you change something like repotting soil, flushing water, please dont expect changes overnight, give it a couple, unless it progresses to get worse

What kind of soil r u using

looks a little over watered.

Thanks for all the feedback everybody, I think that I'm just going to wait it out, the problem hasn't got worse and new growth is not showing any signs of stress, ph levels have also balanced out to nearer 6.7

Ill also maybe cut down a bit on the watering an move the lights back a bit for safe measure.

Thanks again!
