fix.

have you checked under the leaves for spider mite and so on

not mites for sure temp 79 day 68 night humidity 50 percent possitive no bugs

have checked for bugs none

did you use a scope or mag glass to see?

30 x mag glass

live in desert dont really have bugs here

Scoped out= no bugs.
Humidity Good.

Hmmm I would do a safety flush and make sure you take the nutes at a safe level. Wait a week and see if there is improvement.

flush em m8
but as long as there ain't no mites i wouldn't worry to mutch

thanx did one flush still getting worse your suggesting another flush? and what about epsom salts use it or no

already did a flush and foliar sprayed w/ epsom salts still getting worse should i flush again

I cant believe no one asked about the specifics of this grow first......What strain, how old, what is the feeding schedule, how big are the pots, how many days between waterings, light, air ventilation??? Questions like this could really help some one find a better answer then flush....oh yea what kinda medium are they in???
