I need help urgently..my plant is dieing

After a month and half of taking good care of this plant here come the problem. as you can see the brown spot is all over the leaves...starting from picture 1 brown spot start showing mainly from inside out picture 2 starting showing some yellow spot within the brown spot then picture 3 the leaves starting to die out. the picture 4&5 is taken from the tree...this symtom is spreading all over the tree and its killing my tree..one of the plant is turning all yellowish...I need help urgently to rescue my plant..

this plant is under 1000w HPS light day time temp is about 88-93 degree at night the temp drop in between 81-86 degree...PH water i use is 6.6 ... I use combo 24hr nutrient monitor ..the exact same one Divestone has. weired thing is when I tested the PH water using this device if I use just the Ph electrode from the device I get a lower number..if I drop the TDS meter in the same container along with the Ph tester the ph water will change (rised)...

Anywase, I did the trouble shoot on ph runoff water following stinky instruction....I would get 5.1 when in fact the ph water in my res. is 6.6 ...could this be the problem? Please HELP!!!!

well copy and paste the form here.
u got a couple of problems..have u noticed any thing that looks like spider webs on your plants,like under the leaves,the verry top,were new branches meet the main stock?i just zoomed in on the pic and it looks like the red spots could be a calcium deff,what ppm is the water before u add anything 2 it?

the brownish and yellow could be a manganese deficiency, what ppm is the water before u add anything 2 it?my guess is u need cal-mag.if u have to 2 micro nute deff's,there is a good chance you dont have it available in your water.or,your ph's are off and both of those elemts are being locked out,causing problems.i know this sounds stupid but u are testing your ph after u add nutes right? maybe buy a super cheap ph test kit from a hydro store for like $5.00 and compare it to your meter.

i reckon your lamps are to close and/or the temperature in the room is to high. the best temperatures are between 75 and 85.
could also be nute burn and as 'disrupt86' said it could be insects so what you should do is go over everything again, check for insects, get the temperature lower, check your ph and maybe flush your plant to..to check if the light is to close put your hand at the top of the plant and see if its hot..if it is higher the lamp..if you have already done all of what i said well then im sorry i cant help you...good look geting her better though

well if it were heat issues,your leaves would show other syptoms.i would bet my left nut your having ph issues.

Thank you for your respond...the ppm of the water before adding anything is 30...my grow room is free of insect im very positive about that...i did calibrate my combo meter device before use..and i did so every once in awhile to make sure it is accurate...its just throw me off as mentioned in the initial post if i drop the TDS tester along with the PH tester it will change the ph of the water will jump about 7/10 (.7) of it..not sure why...the distance from the light to the top of the plant is about 2 ft. ... since i started from the clone...this is what i did..

I have 25g rez. -- I added GH 3part M=200ml, G=200ml, B=200ml. added 20ml Superthrive and 200ml Hygrozyme...and i've been spraying Growth excel daily..

about a week ago my friend gave me some B-52 so i added to the rez. 4 days later I start to notice this symtom...

disrupted86 - what is the ppm of my water should be before adding anything? how can i change it?

Yes, its a good idea to get a cheacp ph tester for comparison i will do that tomoro..

Oh, what is the ph of the runoff water should be...I tried to raised the water to 10 and drained off into my medium bucket i got 5.4

thanks

your ppm is verry low,u need to add a suppliment,like cal mag keep adding and testing until your ppm is over 150 and under 250.play with it. what kind of medium do u use and did u soak it in pre bufferd p.hd water? so this is the combo 24/7 with three probes right? i honestly couldnt tell u y you would be having these problems as soon as u drop the tds side into the rez.when u pull it out does the ph probe instantly change back to its original reading?maybe clean the shit out of the probes and your rez re calibrate every thing just 2 see it it helps. i will head down to the basement 2 marrow and go through my boxes of gear and see if i can find u the exact instructions off the bottle"i dont need it any more" it should be on the bottle whenu buy it,unless botanicare has changed there labels again.ask the guy at the store he should have product catalogs on a counter somewere.

You could have a pH issue there, but I think that is heat stress. 90 is too hot for a grow room. Put a fan in there if you haven't already, get the heat out. Maybe move your light up some.

the room temp is kinda high but i dont think its the heat issue...actually this combo meter has 2 probe...it measure ph, ppm, temp...I have foxfarm soil..can i use the cal mag that human take to adjusted or do they have a diff cal mag for plant?

one more question - I changed my rez. this morning my ppm went up to 2000 how can i reduce it..

25gal rez- I put 600ml floraGro, 400ml floraMicro, 200ml floraBloom...

thanks

I don't use hydro but I don't think you're suppose to have more than 1200-1500 ppm. If it shoots up it's probably because you put in too much fert. You've got heat damage too.

If you'd really like a diagnosis that counts...fill-out the damn troubleshooting form. (as mentioned a few days ago) This game of back-n-forth is doing nothing to help your plants.

Looks like ph lockout and overfertilizing. But without the info you would provide in the troubleshooting form, (the link is in my signature) all previous guesses are...guesses. No, it's not heat stress.

I'd ditch the Superthrive if using a 3-part nutrient system. The stuff is crap anyway. And these days...it's real expensive crap. Superthrive Myths

I'd also stop spraying the already stressed plant with a product from the world's most expensive additive company until you get them back on track.

I agree with rusty. It IS a pH problem. You even answered your own question in your first post.

'Anywase, I did the trouble shoot on ph runoff water following stinky instruction....I would get 5.1 when in fact the ph water in my res. is 6.6 ...could this be the problem? Please HELP!!!!'

And like rusty said, fill out the troubleshooting form and everyone can get a better idea of what is CAUSING the pH lockout. Adding more calcium and magnesium will burn them at this point, not help.

I still think heat is a problem but now that there's more detail and I look at it closer, I think Rusty's right. I think the problem actually is the automated system or whatever you're using to pump in water and nutes. I doubt if that's necessary. Maybe flush with pH adjusted water and let the soil dry out. Just water by hand if possible. This is just a suggestion as I don't know how your system operates but I'm guessing it's getting too much stuff. It's nice to learn something new. Thanks for bringing this to the board.

Number10: Tap water may be too hard.
Number 13: You are feeding way too much for dirt and causing nutrients to be held in the dirt and causing an acidic over-fert.
You should only water when needed and feed every two or three waterings.
This is why you do the run-off test to check pH. Re read Stinky's sticky and you will see.



NOT A HEAT PROBLEM!!

um 90-95 lights on, is a problem and will affect your out come verry much so.;) tap water hardeness is out of the question. his ppm out of the tap is a 50 u lucky bastard.hardwater is 250 and above "personally i say more like a 300"

During the summer I'm fortunate if I can keep the ambient room temps down to 95. (outdoor shed, middle of the desert) There are techniques to compensate for the heat though. The plants harden-up quickly, and do just fine. Indica's do better than sativa's. Optimal...no. But not a major problem, either.

Feeding daily...? Watering is adding properly ph'd water without nutrients in it, to keep the plant hydrated between feedings. (only when necessary) Feeding is mixing-in the nutrients with the ph'd water. Usually once weekly per manufacturers instructions. A schedule is usually available online these days.
General Hydro Feeding Schedules

When you foliar feed, you are adding more nutrients, micro's and metals. Until you get a handle on what to add and why...I'd stop with the foliar stuff. The GH nutrients have all the nutrients and micro's you need for a healthy plant.
Learn the basics before trying to go pro. :thumbsup:

Hi guy - over the weekend i've been watering it with just tap water without adjusting the water pH...the pH water is at 7.6-8.2 ...i'm afraid to add anything or adjusting anything...all my plant is getting worser and worser...now since most agreed it was pH problem...should i adjust the pH of the water? UP or DOWN since the runoff is at 5.2? I stop feeding the nutrient already...

one thing i dont understand is i've been feeding it with the same schedule (daily) at the same amount of nutrients...200ml-200ml-200ml G.M.B in 25g rez. since i transfered into the soil ..a month later it grow a foot and half tall and it look so healthy..and then all suddenly i got this problem...
