Thoughts on what caused this. Is there an issue I may need to look into. Plants are in 4th week of veg after watering yesterday I noticed this on a single leaf. The leaf opposite of the one with spots is OK. I need to know what this might be or if it's something to worry about. The PH from water runoff was 6.3 feed at 900 ppm every other watering and temps average mid 70s and never go over 85 or under 68. The other pic is just to show overall health of plant. All other plants in the grow seem OK. Thanks for any help.
