Ideas guys?!

o.k guys, plant started off o.k but it has got worse now. Has started drooping abit aswell.

I gave them magnesium today but want to check with you guys. Pics follow.

Cheers

could be heat

and a little over nute maybe try flushing it and venting

Bumped for more ideas..

would like more info on the environment. heat, humidity, type of lights, proximity of the light to the plant. leaves dry on the edges and curling suggest a heat burn.

My bad..

Growing in a grow tent, about 6'6" tall and about 1m square.

250w hps about 30cm from tops of plants (fan blows fresh air in between light and top of plants.

Temp w/light on are 75f-80f
Temp w/light off are about 65f-70f

Feeding about 1l per feed, 2ml nutes. Gave them 2ml magnesium per 1l yesterday and sprayed affected areas.

About 3 weeks into flowering.

could be light burn, is there lots of heat at the tops of the plants? check with your hand, hold it at the top of the plant for a min or so.
the other thing it sounds like a lot of watering. are you letting the soil top dry out a bit before watering. Did you say ferts with every water. if so split it up. water--feed--water or water--water-- feed.
dry margins suggest light burn while the wilting and yellowing suggests too much water and or fertilizers.
good luck

I feed them 1l water a week and thats when the soil is nearly completly dry.

Could be heat burn but its happening on lower leaves and not on some of the higher ones??

Il try moving the light away and see if they improve.

Many thanks dudes.
