temp 78.
growing in soil, some of my plants are from seeds 5 week old
and clones 3 week since roots
ed.

im in soil mixed with 1/4 perlite
under 400hps still vegging.

i water 2 times a week
1 water
1 water with molasses
i have only fed the plants 2 times since ive had them.


going to put some into 12/12 this weeekend.

my temps are 78.

only thing is i dont have any outside air circluating and things seem very humid,
i open the growroom door for 2o mins a day.

but some of my bigger plants from seed are going crispy round the edges.

im not over feeding?
my temps are not too high?
any views why.

its not new growth just older leaves that are doing this
