bit of a problem with a couple of my plants HELP needed PLEASE (got pics)

[oliwog]

ive got a problem with two of my plants one is starting to droop quit a bit and the top fan leaves have gone crispy
the other is just the fan leaves at the top are goin crispy
does anyone know why this is maybe its a heat problem but i dont know for sure. i leave the cupboard doors open slightly when the lights are on to let out more heat as it does get fuckin hot in there (need to invest in a grow tent or somethin)
the others are fine.
ive just recently changed the pots over as i noticed the growth was bein stunted, i know this can make em droop but not crispy
and besides it was a few days ago i changed pots
i got a feelin the droopy one may die and possibly the other so i need to know if there is any way i can prevent this
if i do loose 2 plants its not a major issue as i got 10 all together but still thats besides the point
and also i dont want the same to happen to the others
anyone that can help please do
the droopiness has got a bit better since lights out its perked up a bit but still not looking too good

what nutrients are you feeding them?

[Horsefeathers]

What kind of lights do you have and how close do you keep them to your plants?

--------------------------------------------------------------
I'm no expert, but I did spend the night at a Holiday Inn Express.

that is definately a heat issue with the tops crisp like that what lights are you using and how many of them, what is the space size of the area as well?

do you have any fans in there at all?

[oliwog]

right im using a 600 watt hps light i have it as far away from the plants as possible as they are rather tall its a good 8 inches give or take 1-2
ive only got em in a wardrobe dont know the exact size but so you can get an idea i can fit 12 plants in 18cm diameter pots in there
it is about as tall as me in height jus bout 5.8 ft
i also have 2 envirolights in there at 125 watts each they are heat and energy saving tho so dont give off much heat
its the 600w hps that gives off the heat
ive tied 2 plants dwn cos they got too big for the cupboard
i use Biobizz topmax for nuts although i havnt fed them for about a week jus watered due to a heavy feed earlier on last week
they are in flower so need to know the best way to sort this as you can imagine its not the best stage for this to happen to them

oh yea i have a small fan in there im gettin a bigger one on wednesday
the fan jus seems to circulate hot air tho

[locomark]

Removing the hot stall air will do wonders. I assume you lamp isn't aircooled.

[oliwog]

no its not aircooled
i do quit often open the doors fully every hour or so
and generally i have the doors a jar to let out more heat.
can i make my light aircooled????

hi oliwog you replied to my thread earlier , you said that you had similar probs 2 mine, but my plant is def diff frm yours ,my main cola is about 18 inches long and about 6 inches wide, i have no external air intake ,but i leave door mid open all day and temp keeps down ok,i have given no nutes exept tomato feed when in veg state,

[oliwog]

yea welshbud i think il have to leave my doors open more from now on
my buds on my mango arnt as big as yours but they comin on i think i may get a half oz off it
not exactly brilliant but ok considering most of the veg and flower has been with one envirolight sittin jus above it
envirolights dont really give off enough light to get a good flower unless u got like fuck loads of them and only a few plants
my other 10 strethed to 4.5 ft tall within 2 weeks of flower cos of the envirolights (i think) they were put onto flower at bout 10 inckes tall
although the seedbank did mention they can reach height of up to 1.5 metres
but i assumed that was outdoor
oh well wots done is done lets jus hope they turn out ok
next grow will be much better ima try get me a strain called PINKY (spumatic)
or black cherry from TGA seeds in canada
looks like some real nice strains
il log it all from the begginnin still you all got a couple months to wait for that tho
