ok..first off yes I know I have mites..treating now...but I have these rust looking spots that start in the center vein of the leaf. any ideas? can't find any similar pics on any of the forums.

mg soil ,,,300 watts cfl,,,2.5gal. pots,,using rainwater the last few weeks,,ro water also..flushed 2 weeks ago..1/8 strength nutes (12-55-6) last week..molases and epsom salt at last watering (3 days ago) @ 1 tsp each boiled and added to 1 gal. water,,,12/12 light for 4 weeks 2700k..temps night 76-77 ,,day 80-82 humidity..night 60% day 55%... bagseed,,trying to figure everything before using quality seeds.420 011.jpg420 014.jpg420 016.jpg420 017.jpg420 018.jpg420 020.jpg
 
I looked at a few bad leaves under 60x micro...looked like fungus,,so i researched and believe it is a fungus,,,got some copper soap fungus med. sprayed as directed at just short of max dose as its bad. if this works i'll post info updates.
 
Post pics later..I'm curiuos how the buds handle it. Personally I don't like stuff on buds.
 
I know what you mean on spraying buds,,,on the bright side this was just test run with bagseed so i'm not out anything if i just trash it later,,,great learning experience for my next grow when i use good seeds. the stuff for the mites and the stuff for fungus are both organic ,,no chemicals , i will keep updates with pics,,,one thing i did notice,,i think the fungus got way bad before i knew what it was and most of the white hairs,,,the ends all turned brown,,just have to wait and see
 
Nute/salt burn. Flush drain repot and change to hydro nutes every watering flushing with ph'd water every 5th feed. Your current feeding regime is crap and causing these issues. Also im sure you havn't monitored the ph of every watering/feed at 6.5 .
 
I wouldn't boil water and give it to my plants,yeah some water has toxins in them but boiling also kills the beneficial chemicals that rain water don't contain.
