Re: brown spot's

Looks like it could be a Potassium deficiency. I recommend ensuring pH is optimal, and/or flushing/changing the reservoir. Pull off any of the bad leaves as well, you don't need them plus they'll just affect your overall grow feeling when you look at them.

Re: brown spot's

Ok, If you can a bit more info would help, How old, what nutes have you given it & how much, Also it looks like youve got a CD covering the stem, if so have you thought about the possibility of burn spots from the light being reflected and turned into little lasers that can and will burn your plants. With the tips looking the way they do, It looks to me like a possibility of nute burn, If you,ve fed it a bit to much, or to early. Just some other things to look at.
Also, if you have fed it, what was the tds of the mix?

Re: brown spot's

sorry i didn't think about giving more information...

er'm she will be four week's monday coming,
er'm iv given it (vitalink plant nutrition easy hydr growth feed) the reservoir is 3 leter and iv added 15ml of the feed, what do you mean tds? what's in the mix in the bottle?
the grow room tem is 28 degrees celsius,
i didn't think of the cd doing some think like that but ill keep it in mind thank you, i only put it over there to stop the light getting to the water and turning it green and corsing algae but ill change it and see if it help's

sounds like trouble to me. Some sort of nutrient issue. My guess is potassium.

Potassium is involved in maintaining the water status of the plant and the tugor pressure of it's cells and the opening and closing of the stomata. Potassium is required in the accumulation and translocation of carbohydrates. Lack of potassium will reduce yield and quality.
-
Older leaves are initially chlorotic but soon develop dark necrotic lesions (dead tissue). First apparent on the tips and margins of the leaves. Stem and branches may become weak and easily broken, the plant may also stretch. The plant will become susceptible to disease and toxicity. In addition to appearing to look like iron deficiency, the tips of the leaves curl and the edges burn and die.

Potassium - Too much sodium (Na) displaces K, causing a K deficiency. Sources of high salinity are: baking soda (sodium bicarbonate "pH-up"), too much manure, and the use of water-softening filters (which should not be used). If the problem is Na, flush the soil. K can get locked up from too much Ca or ammonium nitrogen, and possibly cold weather.
-
Usually not absorbed excessively by plants. Excess potassium can aggravate the uptake of magnesium, manganese, zinc and iron and effect the availability of calcium.

hello motherhugger and thank you, that has help't a lot...

i was useing water softner anti chlorine drops, So if flushed the grow media with fresh water and cleand out the reservoir and put fresh water in there as well with nothink in to flush all the water softner out and nutrient i think iv over feed her with, I was going to do this for two or three day's and see if it bring's her back to life, And see if her leave's start to pick back up, I had just gone back to water after her leaves started to drop but was still putting the softner in the water witch i think i may well now be after what you'v told me... thank you and thank you all for your help and suport it very much appreciated
