Hello, first time posting in forums and thank you for your time reading this. Wondering on help for some issues I'm having relating to some leaf issues. Some of the lower leaves are showing what looks to be something calcium related but cant figure it out. Only certain plants have it. Coco coir, drain to waist, 30% perlite mix, air pots, gh flora series nutes, ec about 500-550 in, ph about 6.2, about same runoff, watering once/twice a day, 10-20% runoff, filtered tap water coming out about 160ppm (500 scale). Great white Benny's, late veg, temps about 78d 73n, r humidity steady 60-62, black dog 600 and my 600. All plants overall look healthy, few not so. I'm wondering if I'm getting some lockout from the cal mag as I use about 5tap per 10 gallons of water. Tap is filtered to get chlorine out, but would still have cal and mag in it. I may of course be under feeding cal mag too. Some plants drinking great, few are not which those seem to be the ones affected. Any help would be great. Tyty

Looks more like light stress from reflective hot spots to me... The crispy breaking fans def look like light and heat stress over all they look good but your burning them up with nutes or light it's not lockout the plants being stressed will curl the burning fans in an attempt to stop evaporation and reduce surface exposure to hot spots. Crank up the wind blow those babies an try some misting or increase rh
