Yellow Leaves

my outdoor plants are looking worse and worse. one of them has a phosforous deficiency(discolored fan leaves and curling) and now all 4 of them has droopy leaves all over the plant. should i be worried or is this a passing phase when they go into flowering? theyve been 1 week flowering.

Hey i have a problem with my girl, her first two actual leaves (not cots) started with a yellow spot and eventually turned completely yellow. She already has her 2nd set of leaves in and they have a tiny tiny yellow tip on them already.

Too much heat??!! Whats going on? My lights are only like 4 inches away it can't be light burn..

I have the same problem, and mine was too much heat, mine are 15 days old. If you a using MG so might have been unlucky and it could have found a nute crystal before anything else.

if the tips only....then prob heat and the same prob last night my girl turned on the HEAT.. i almost killed her ha. but they are all good....thankfully

Really...Cool then i need to rig me up a ventilation system FUN FUN

Thanks guys!

It might be magnesium deficiency. I had these exact symptoms. See if your leaves look like mine in my journal. If so, use a weak solution of Epsom salt (sold at any pharmacy for cheap). One teaspoon per gallon. Foliar feed. Usually mag deficiency is rare, but it happens like in my case where i burned my plants and they got too much potassium, which in turn blocked magnesium....this is a common cause.
