overfeeding or deficiency,,,,,help please

hi everybody i m at the 4 week in flowering and only the very top cola are aving this wird curly up dry burned like leaf . can anybody help me with this problem so far i got totally different opinions from friends what do you think .

looks burnt and crispy. maybe your lights are too close or your EC is too high. what is ur PH, EC and how high are your lights?

the plant is under a 300 w cfl light at about 6 to 10 inch away from the light bulb the ph on my water is 7 .

you got a lock out probably. if ur doing soil adjust your PH to 6.8 and if ur doing hydro lower it to 5.5-6

Dam it!!!! I had to erase all that I wrote.
Bottom line. How do you have anyway to know what this guy needs. He has given next to no information.

Ok, I am chilling. I think Urgod is on the correct tract. But the amount of information is not enough.

You need to give way more info-rmation. temps/humudity/PH howq often fed, how much all of it.

But if I was to GUESS, I would also say you threw the PH out of wack, or over fed it..

first off...7 is perfect PH for soil. secondly...why is that CFL 6-10" away? theres no reason for it to be that far away...ill give you the fact that it puts out slightly more heat, still 3-4" would do the trick though i do agree it looks deficient...also looks like heat stress, so find a deficiency that exhibits the same characteristics of heat stress, and theres you solution...and more info . is usually more helpful.
