the lights are above it.

today i changed it to this cuz i thot 2 much light was being wasted, so i hung tin foil behind the plant and cut off half of the space of the room that wasnt being used, and put those 2 lights right next 2 it insted of above it, and used tin foil to reflect the light back at the plant:

so im using 3x150 watt fluoros= 3x2600 lumens= 7800 lumens for about 3 sq. feet and 1 plant. how is this? is it enuf?

also, i think this is a mexican redhair, fairly common in phoenix, AZ, but someone told me that red hairs were a P deficiency, is this true? i am using 36 6 6 ferts but when it developed the red hairs i was using 5 30 5, i switched bcuz i heard high N was for vegetative, and P was for flowering... but the red hairs cant be from a P defeciency if i was using 5 30 5 when they first showed up, can they?

lol 1 more thing: is this too droopy for the leaves to be at night? i konw they groop more at night, but they are kinda droopy during the day and this just seems really droopy to me:
