3 or 4 leaves on 2 of the plants have some light browning spots, and the others dont have any signs of stress. I'm not sure where the brown came from, what would u suggest spraying on them, just water? i really dont have any organic pesticides / foliars because i've never had pests before. i really dont see any bugs on anything even under my scope

My pH pen is lost in a pile of junk from moving the room over i will have to dig thru and find it and re calibrate it i've been having some troubles with the pen but i dont think ph is the issue here. i have a rough idea of how much i need to use, i know the water from my water line is generally about 7.7 for god knows why, i use a water filter that u change every 3 months and it takes it down to about 7.2, i then add roughly 9 mL of pH Down to the 27 gallon resevoir which takes it down to around 6.2.

well den u hav to give exact info as to how r u growing....based on that probably hope someone including me can find out the main cause of this problem.....
are u growing it in soil or soiless or hydro ?
if its soil ...then i think u shld keep ur ph higher...i wld recommend 6.8 ...cuz addition of nutes will bring it down to around 6.5 which is ideal ...if hydro .....go down to 6.4 or 6.5 which will comdown to 6.2 cu of nutes .....
if ur using artificial fertz den u need micro nutes to add as well ...giv info abou ur grow...i mean evrything

Brown little spots on leaves could be either a potassium deficiency or manganese deficiency.
