3 G force under a 600 watt HPS light. about 18inches above canopy. they are on the Foxfarm soilfeed schedule. with an addition of magical, Superthrive and Sugardaddy added every watering.I thought they were getting too much nutes but they dont look burned at all its only the fan leaves on the budding stems that seem to be affected. THe bottom leaves are cupping some but with very little spotting if any. However on all the flowering tops the fan leaves have spots and are yellowing. def looks more like rust than purple or anything. this is my 2nd run with the G Force and they did the smae thing last time. They looked beautiful til they started flowering. IDK what to do. the spots seem to start at the veins and work outward. temps are day=83 hum.50% night=73 hum. 50% they have co2 supplemented as well. please give me any advice. they are at 34 days flowering right now.
Rust colored veinal necrotic spots please help ASAP

They look super dry and crispy. I can see the salt buildup from here, I wouldn't add any more nutes for a week, just water. It looks like pH too, probably from nute buildup. After that, just use nutes every other watering. Also, if you're not watering enough, the roots will get salt buildup and look like that because they don't have enough moisture to dissolve the nutrients. Edit: Don't water too much though, moist not wet.
