Seedlings again.. HPS problems i think

Discussion in 'Sick Plants and Problems' started by davidppeters, Feb 16, 2009.

  1. I started my seedlings out on a t5 but they were stretching bad so after one week i moved to the 400w HPS... No picture but the very smallest newest coming leaves are browning, I didnt give them fert yet.. so its not that... IS the HPS at 4 feet away burning them? Only the middle new leaves are effected.. and only some of the plants are effected.. They are now two weeks old... Help.. somebody tell me.. Should i make some sort of light filter to soften the light

    are the fan leaves getting wet at all when the 400w light is on? if so, misting possiby could burn leaves, the water acts as a microscope intensifying the light, thus, burning the leaf..

    otherwise leave the seedling under the t5(efficient and much cheaper to run) until they are more estiblished(bigger with more of a root mass, and less like to DIE.)

    and are you easing them under the 400w? going from t5's to 400wHID, i'd put them under the 400w for only a couple hours at fisrt, and increse each day til you decide they can stay for good......

    just a thought...
