Plant Health

[BuzzinBobby]

Hey everyone,
This is my second grow. The first was with CFL's and this one was started with CFL but i switch over to a 3x100w LED light. The plant really took off with the LED, in fact I am having some issue over how big it has gotten. Anyway i am noticing a few leaves starting to have their sides curl a little. I am reading a lot about cal/mag issues where LED lights are concerned. Would anyone care to share thoughts as to your opinion of the general health of this plant? also, should i introduce cal/mag into the feeding schedule?

Plant = bag seed unknown breed
medium = FFOF
pot = 4 gal
nutes = FF grow big during veg and FF Tiger Bloom now(flowering)
Currently in 3rd week of flowering
temps 70 - 79
Humidity 45 - 60 %

Look fine to me, usually when cal-mag problems start they will (Mag) get lighter green/yellow leaves between veins, brown spots, and usually happens on the lower leaves first/moves up or (Cal) little rust/brown spots start showing up usually on newer/top leaves, stems will be weak.

Since you're using LED, I would supplement Cal-Mag in at about 2.5ml - 5ml gallon, if using RO water mix cal-mag in first before nutrients.
