what about the pic of the big dark green fan leaf? I'm not saying it's nute burn, but i certainly wouldn't say it's fine. I have almost identical brown rust-looking spots on one of my plants. If not nute burn what could in be in your opinion BUDS?

check the PH of your soil first, then go from there, could be Mag deficiency, then again it might be a number of factors. Check out the other forum

What is your Temp and Ph? Check how close your lights are and the temp at the canopy. It is definitely a stress of some kind, but it does not look terminal. Off the top of my head I'd say your adding 3 phosphorous and potassium dense additives fairly early into flower, take care you're not adding too much...could they be locking another nutrient out? When in doubt about nutrient burn, the answer is flush...if possible with your system.

Bingo Mr. Beans, that's heat burn/stress, move your lights up and try to keep your temps under 85ish

Always check the enviro before trying to fix plants for nutrient related problems, you might really fuck something up chasing nutes, checking the enviro is easier to correct if you diagnose that wrong. Just my 2 cents!

I would agree with you guys except my plants are outdoors and I have almost identical brown spots on the leaves of one plants. So it's definitely not a light issue, at least not in my case.

the temp is about 75 to 85 , the soil PH is at 6.0 to 6.6 and the light might be a bit close 250 hps about 12" from the plant but i have a nother plant thats closer to the light then this one and its fine,might be the strain? its a "alien white fire"(super lemon haze X bubblegum).the smaller one with the brown spots is a "purple master". but THANKS for everyones help!!

Do you have a thermometer at canopy level as well? If not your temps are actually higher in there, if the one in the pics is what you're getting your temps from. Also do you have good air circulation?
