Unique leaf burn

Hey guys, I'm new to the forum and have received great information from everyone countless times. I'm not exactly a beginner but this is the first time I've actually put effort into an indoor grow. I'm having a problem with one of my plants and have googled leaf problems for 2 hours and absolutely nothing looks like what I have going on. Here's some info:
* 4 plants
*Seeds- unknown freebies from an online store
*Grown in 5gallon buckets with organic soil. 12 holes with 3 inches of stone in the bottom for drainage.
*Lights- 2 blurple no name l.e.d lights consuming 85 watts each, with 196 3w smd's ,plus 1 hps 250
*Lights are 18 inches away
*4x4 grow space with floor to ceiling mylar reflective film
* Second week of flowering
* Water in is always 6.0 and run off is always close to 6.0
* Nute npk- 4-25-8
Room temperature stays between 65-72°f during the day and 58-62°f at night. Surface temp of leaves is always a couple degrees lower.
* Humidity is around 40-50%
*10" circulating fan
* new air in from from outside comes in at the bottom then is sucked out through a carbon filter extractor at the top and blown outside

Not all my plants have this problem, it's only about half of one plant. All the others are nice and healthy, not a spot on them. Also, this is one of my shorter plants. There are ones 10" closer to the lights that have no problems at all. I was thinking light burn because only the top side of the leaves are dry and crispy,the underside looks unharmed on most of the damaged leaves but what makes me think it's not light burn is the fact that it's random leaves from the top and bottom of the plant. They all get the same attention and nutes. Please help

I think you’re right that it’s a little bit of light burn, and just one leaf primarily. I don’t think you have anything to worry about. Watch for more of that and if you start seeing it raise the light a bit.
