Splotchy discoloration on leaves in veg

dangerous thing to suggest either way... looks like you don't use a ton of different products... guaranteed analysis labels can help eliminate possibilities. Symptoms can be from tox or def. mus consider recent behaviour, substrate, pH etc etc... 1st -- pH 6.5-6.8 in soil. what you put in, what the soil is... keep it in that range. Looks like oyu use pH products, so probably doing this. 2nd -- watering habits. looks like it is always wet. Are you letting top 1" dry between irrigations? Also, when you do irrigate make sure the entire pot is saturated. Some runoff ensures this. When adding water with no nutrients, maybe shoot for less runoff, but do ensure it gets saturated. When fertilizing make sure you get a healthy 20% runoff. this will ensure a happy eqiulibrium in your soil results. As long as you allow for the wet-dry cycle, it'll be rare to see any droop from watering at all. if these two things are all good, then you can use recent behaviour to eliminate possiblities. Remember it is always easier to add stuff later and much more stressful to the plant when trying to dilute the substrate. Your soil likel yhad a healthy amount of nutes the first 6-8 weeks, but will rely more and more on fertilizer toward the end. this is when the extra runoff with fertilizers is key to maintianing fertile soil. re-fortifies it with proper balance, hopefully. I hesitate, because i see multiple symptoms that don't jive. This makes me think lockout, but your fertilizing habits are not overzealous, either if that is blue-ish in real life, i'd say some p-def is there. I see some canoeing, whihc coudl be overnuted or heat/humidity related. interveinal chlorosis in one pic. some dark veins too. So, consult a leaf chart... check lables for what you provide, and make a good educated guess. i have a leaf chart linked in my GD.com main profile comment section, just click my name. scroll down. it is a link to a picture hosted on GD.com -- nothing 3rd party or offsite invovled. also, have a PPM calculator for nutes, but no guarantees it works for w/w% listed labels. also, us standards for p/k labeling. Can find alternatives through google easily enough too. remember, if w/w% and it doesn't handle specific gravity, it is a bunk ppm calculator for those types of label values.
