I have a S. 'Judith Hindle' that has about 14 pitchers. about 5 of them are not all green. the tips of some a brown like tree leaves during fall. i don't understand the reason for this. i got this plant from Lowes and it was fairly small so it couldn't have been that old. could it be that i have it too close to the light? or could it be from lack of real sunlight? i give it plenty of water and about a few hours worth of sunlight once a week. should i up the sunlight days?
