HourlySmoker

Can you please look at the pics and tell me what is wrong?? I am hurt and typing with broken bones so please read my journal for my info about my grow. It would make me feel a lot better when I go to the hospital if I knew my plants are alright. I cant find a solution in my grow book. The leaves look black and are curling up.

Hey Hourly smoker , I read your journal . Sorry to hear of your med probs .A couple of ??s . What are you using for ph down ? Do you have that ozone generator in the cab with the plants or in the exhaust of the filter ?

Get well soon FMJ

I am using a PH down powder from the local hydro store. I have not recieved the ozone generator yet. When I get it then I will set it on top of the cabinet so it is right by the exhaust fans. Any clue what is wrong with my plants?

"Rockclimber- My tap water is 192 ppm and PH of 8.0 with nothing in it. It takes a bunch of ppm of PH down to get the PH correct. I have been reading about H2O2 but havent really figured it out yet. When should I add some?? What does RO stand for? "
192 + 350 = 542 You're running 1000 ppm 448 ppm of ph down sounds mighty suspect to me . Are you sure of your calibration on your ph tester ? Do you know what the powdered ph down consists of ? Even with an 8.0 starting ph it should only take a small amount of ph down to get to 5.5 . I use 30% phosphoric acid ( liquid ) for ph down . Nitric acid would work better in veg as it adds nitrogen to the mix but the Phosphoric would work too . When i first started i used a ph pen with a rubber cap on it and forgot to take the cap off once and wound up overdosing with ph down . My plant looked an awful lot like yours as a result . I recommend getting some either nitric or phosphoric to use for ph control , Check the calibration of your ph pen and putting your plants on a plain water flush until you're sure of your ph control . I think the powder is the culprit so use white vinegar to bring the ph of your tap water down until you can get set up with the above . The leaves that are damaged will not get any better but if you still have green new growth you can pull this off . How's your arm ? FMJ

Let's see...you've been givin' lots of advice...yer chasin' fires all around.
Hmmm...you were told about humidity? Needs to be 60-70%(optimum) in room for veg. You put a wet towel in a bucket to raise humidity. Do you know what is is now? Hang the towel up in the room, it will work better that way. I use 3 hangin' towels and a small humidifier. If the humidity is too low the plants will over transpire and will burn from the nutes. If ya don't have a humidity gage...get one they are perty cheap.
I have never believed yet that yer prob was lack of nutes. The roots look OK so I don't believe that H2o2 is going to fix things. The burned leaves will not heal. So we watch the new leaves to see the progress. Those WW's at this stage still don't need a lot of nutes 200-300 PPM.
As I said in yer other thread (which probably should be merged with this one), When ya over nute, a system flush is in order. First order of buisiness: Fix Humidity quick
Flushing: should be done every 2 weeks and or when ever ya overdose yer babes.
