see what youre saying makes sense....but....why would only one leaf show this...and at the middle of the plant? why wouldnt new growth have the same kind of issue...if it were on more leaves id be like "okay hes right" but with one leaf is this possible? the spots when i look at em with a magnifying glass they are see through almost...a transparent yellow brown....ive been following fox farms feeding schedule...and am using fox farms ocean soil or whatevr....ive never thought of ph"in my runoff water..if that water is off how do i adjust soil ph? i have been using the hydroponics ph up and down kit...and a ph tester...(but this is all for water prior to watering....im starving for this green knowledge....enlighten me....PS packers BLOW.
