Help burning!!

Hey guys looking for some help here. I have 4 girls I just switched to 12/12 last week. I noticed today one plant seems burnt!!!! There in a 4x4 with 600 watt hps that is currently 20 inches above the canopy. It's 80 degrees and 60% rh in the tent. With 2 circulation fans running. All the girls are being fed cyco and I mix all 12 gallons at the same time. You can see in the pics the rest are ok. Any idea what's up???

What is the temp at the canopy? That is what you need to know. 20" above is a little close in my opinion. Back off to 2' and check temp again. I personally would not go any closer than 2'. Good luck

i was thinking that but all 4 ladies are fed from the same reservoir. all the other plants are fine

trying to get some pics uploaded dont know whats going on with loading pics lately

just did a flush to be on the safe side.

some plants feed less than others

my ppm is at 1165 well under the recomended 1400 and my PH is 5.5 my last grow with the PE i ran the same ppm never a problem these two girls are clones from my last grow.

That is definitely not nute burn. I'd move the light back and be real gentle with it. I recently had 4 plants all show the same symptoms. My temps were 80-90 degrees for a couple weeks. It sorted itself out after I cooled down the room and gave them double doses of silica

Your ppms aren't a problem, nute burn is going to look like brown tips at first. How long has the plant looked like that?

since yesterday afternoon when i checked on them

Its only been a day or two? That is quickly progressing, its possible there are a few things going wrong here. I would start with the temps/light distance and see how the plant responds

i raised the light from 20 inches to 24 and turned on the ac to lower the temp a little. and i did a flush on her any way

Perfect, hopefully that will solve the problem. Otherwise we'll have to look into other solutions!
