Possible Nitrogen problem or??

Just had a quick question. I've got a single female growing inside in a bubbleponics setup. Changing the water once a week and cleaning the system out. She's in the 4th week of flowering and I noticed some dry spots on a lower fan leaf and a few more on the top of the plant. Any ideas?

most deficiencies are usually caused by pH imbalance or a toxic salt buildup. try taking an EC and pH of the medium and see what that tells ya. that is unless your making your own medium or fertilizers.

Did you by anychance spill some of the nute mixed water on the leaves? It will
sometimes burn your plants depending on what type of light your using.

My Ph is 5.8, I did pour some on the lower ones so that could very well be it. The dead area's on the top really look like they hit the lights but they were a few inches away so I'm unsure of those.

no, if it was spillage on leaves they would have dead brown burn marks.these plants have a classic P def imo. A plant at this stage of heading requires extra Phosphorous
