sorry to take so long but i started veg after my 5th set of nodes and was on an 18-6 schedule for about 14 days before switching to flower... the problem is... i split in flower and if im correct, i believe thats a no no. ne ways ... we had an MH running through seedling veg and the first 7 days of flower before switching to HPS ... There was one day I went in mid day while the light was off and did work... i had the door open with a halogen running outside of the room, and i feel as though that could be another possible source of error... As soon as i find the charger to the camera ill be updating more pix and what not... maybe we can figure this out
