1 month into flowering, what is wrong?

I know this should probably be in the plant problem section but there are way more people viewing this forum and I need help asap. My plants were looking great and everything was fine and then I left for the weekend and when I came home one of my plants looked terrible. I was thinking it might have burnt from my light being too close, but I have 4 other plants that look fine so Im not sure. Any advice on what is wrong would be great.

it's either lacking nutes, or is nute burn, you should have a good idea of which one.

I've been giving it tiger bloom at about half the reccomended dose every other watering and some molasses every few waterings. I was just confused because it was only the top of one plant and all the rest of the plants are fine. Should I be giving it more of the tiger bloom or less?

I'm not sure, try going one way or the other, trial and error is usually the only way to know for sure.

I'd try a little less first.

Light burn...?

Are you PHing everything before you add it to your plant?

That looks like light burn to me. Some plants are more sensitive to heat than others. I did the same thing, burned one, the rest were fine. If it is light burn it will heal up and keep going.

Ive been checking the ph everytime I water so I dont think its that, but Im pretty sure Someguy and JAy_normous are right. The only plant that was effected was the plant that was closest to the light. I raised the light about 10 inches so hopefully the heat was the problem and nothing else. Thanks for the help guys.

looks cooked back the light away or tie the fucker down
