    Default Leaf cupping

    Hey guys/gals,

    I'm a complete newb to growing so.. please bear with me.

    I've been experiencing some mild cupping of the edges of the leaves on my baby.

    I don't have the post count to start a diary yet... but I've put up a brief timeline and description here ...

    Grow medium is 35/35/25/5 organic potting soil/ organic garden soil/ coir / vermilicite

    Light: 2kw Bestva LED

    The Grow room is a makeshift reflector (aluminized blanket hung around the light ...maybe two foot diameter.

    Average daytime temp is 88f night time is 72f

    Average RH: 35% (as low as 15 and as high as 50)

    water and or feed PH is 6.0... run off PH is 6.2

    I have no idea what EC is .. i currently do not have Cal-Mag.. i'll be getting some soon though. My tap water (well) is extremely high in Calcite

    I've used SuperTHrive and Fulvic Acid to balance PH in every watering.

    Nutes the 4th week (1-3 was water only under a sub-par light) was general hydroponics trio at 1/4 teaspoon/gal.

    I upped the nutes on week 6 to 1.5, 1, .5 (general Hydroponics teaspoons per gallon)

    I've kept her on the dry side most of the time and i've only soaked the 5 gallon felt bag twice.

    after noticing the nute burn I flooded her .. and the burn seems to have stopped and the growth is picking back up.
