leaves getting yellow spots *pics*

anyone know what this is? its only a minor problem and these leaves are the worst of it. my friend also had this last month and he couldnt figure it out but was using different nutes. im thinking either too much or not enough nutrients. its in soil. i always ph my waterings and feedings to 6.4 - 6.7 its not bugs on the leaves. i know what mites look like and how the leaves look from them and im 100% sure its not them. it almost seems like its forming in a pattern which is why i think it may be nutrient related. im using botanicare full line. i usually feed every 2-3 waterings. i do have fungus gnats but they are a minimal problem because use dr doom bombs often. thanks

did a little reading, is it possible it could be light bleaching? although why whould it start now? i do have my lights very close to my plants and the hoods very close to each other but its comfortable anywhere i put my hand.

*bump* anyone?

looks like nute burn to me

thanks. +rep anyone else any ideas? im also starting to think nute burn. i dont think its light bleaching because it not on my other plants some which have parts even closer to the light.

nute burn starts at edges and tip......not between the veins. whatcha usin' fer water?

i know you've already looked into it... but it looks like classic light burn. You don't have to have high temps to be burned by lgiht. scroglodyte is right that it doesn't look like nutrient burn.

i thought light burn but its only on the 1 plant. its also sorta on the middle area of the plant. if it were light burn i would think it would be more towards the top where the light is even more intense. i do run my lights extremely close though because my hoods are so big and have such strong ventilation. i dont see this on any of my other plants which are just as close if not close to the light. although they're different strains. thanks bro

just regular tap. i usually let it sit out overnight. i also sometimes reuse my dehumidifier water, isnt that the same as RO though? i do ph the water to 6.4 - 6.7 before every watering and feeding. i also have a minor fungas gnat infestation but been keeping em at bay with captain jacks and dr doom. i spray a dishsoap mixture also on the bottom of the treys cause they like to hide there an go in and out of the holes in the grow bags. dish soap water is an instant kill. i dont use a lot though cause im afraid to fuck up the plants. thank you so much for looking into this. also i use botanicare pure blend pro nutrients will all supplements. i reduce the main ones by 75% like the instructions say when using supplements. it says to feed every watering but i was getting burning so now i only feed 1-2 times a week. also could being rootbound cause this? my grow bag is a 5 gallon and the roots feel very compact. plants seem to drink a half gallon every day. my room is pretty hot though like 85F.
