hey dnb, I live in england so know you can get them from growell.co.uk.

Not sure about the rest of the world. Look around a bit ...

I just had a look at the ph testing equipment sold in america and man do you have a shit selection. That is a bummer dude.

Now I understand why evry1 has got a digital ph tester in america...

I added nutes as well after I transplanted hopefully the plant isn't going to burn, does anybody know in the states where can I get a good soil and fertilizier ph tester?

plant is getting worst, I've got a digital ph measerer on the way should be here in a few days, what should I do when it's here? should I just try to flush it out with plain distilled water, or I could do that now, since distilled water is at 7 ph, right? and does everybody agree this is my problem, ph? it's in a 2 gallon container, soil is pretty wet and was last watered on sunday.

I just took a couple pictures, but all the leaves are turning like this.

ur plants might still be showing those signs coz of the low humidity aswell, u should definitely point ur humidifier towards the inside of the cab (or just behind the intake fan) to help it go up and also put a couple of wet towels in there too, youll find it helps quite a bit (if kept wet regularly, my 2 towels brought it up from 40 to bout 55% in the small cab) place it in direct "sunlight" of ur HID so it evaporates more and faster,
otherwise, imo (to be taken lightly, only done 2 grows to date) u should probably water them with distilled water only since u added nutes on sunday and they are in fresh pre-fert soil, and hopefully the higher RH and better pH will do the trick,
Good luck, hope they recover fast

do you just put towels at the bottom of the cab? or do you hang them? it's a wood cabinet, i'm thinking it might mess up the cab

u can do both if u want, or just cover the floor with plastic sheetin and crank them in between/around the pots i guess this prolly is safest for the cab, but once u have that humidifier going properly it should bring humidity up as needed and keep it constant, which would b much less hassle than keepin the towels moist all the time (althogh much more costly electricity wise, dunno bout humidifiers but dehumidifiers use like 2000W)

Also on an other note, to answer one of you earlier Qs, i think the recommended RH for flowering is 60% for the first two weeks, then crank it down to 45-50% for the rest to help prevent bud rot etc...

what about digital ph nutrient testers and soil testers are they the same?

Digital ph nutrient tester reads the ph of a liquid, it has little VERY FRAGILE glass bulb on the end that u dip in the liquid, whereas soil ph testers, from what ive seen, are a metal rod (bout 20cm long i think) that u plunge into the soil and this reads the ph of the actual soil. I dont think u can use a soil ph tester to test ur nutrient solution, as it is already quite innacurate for the soil (aparently, i have not used one, i have the other sort). Digital pH meters are the best bet i think, they are pretty expensive but they will prove to be usefull im sure this is a link for a uk source although i think ure in usa right? http://www.hydroponic-shop.com/product_info.php?cPath=33_80&products_id=351
itll give u an idea what they look like neway.
Oh yea, and if u get one of these digital testers, make sure u also get some calibration fluid too (it is recommended u use two, one @ pH 4, and one @ pH 7, but the one at pH 7 shold be enough as u will be testing solutions in the range of 6-8 (hopefully!), if u were growing in hydro, u should get the pH4 as the rez pH u will be testing will be closer to 4 than to 7 (5.5-6).
Hope all this makes sense

Bingo! Youre on the right track, the TDS meter measures nutrient concentration (parts per million) this could be handy too, but not as useful as a pH meter which the site u linked me too also sell, and they have the calibration fluid too: https://www.htgsupply.com/productdetail.asp?productID=181
$50 for the meter, see how the hydro shop is a ripoff! just a tip tho: if u order it yourself, you should send cash to them not pay with your credit card and dont get it delivered to ur grow adress, it will take longer but u cant be too safe imho...
If u want it quick (which u probably do) u could ask a good friend to order it with his card and get it delivered to his place... :chin:


Edit - the "Hanna Checker Pocket-sized pH Meter" from that 2nd site is fine also
:yes:

Edit 2 lol - sorry, there isnt any calibration fluid @ that first site, but they have some on that superior growers supply site : http://www.superiorgrowers.com/product_details.php?id=1519

thanks for the help, but I'm still unsure about this calibration liquid stuff how does that stuff work?

basically, when u get your pH tester and turn it on, itll indicate a certain number but u dont know if it is the correct value. So u take your calibration fluid (for ex at pH=7.0) and dip your tester in there. The likelyhood the tester will read 7.0 is very low, so if it doesn't read exactely 7.0 you have to calibrate it. This is done by adjusting a tiny screw (with a small screwdriver usually provided with the tester) until the reading displays exactely 7.0.
I find I need to calibrate my pen before every use (couple times/week) as it deviates a bit (bout .5 pH either side), i think its just because its quite a cheap one, but it does the job. I doubt u have to calibrate the $200 meters every week...

so what are those calibration liquids for?

In other words calibration fluids are for making sure the pH meter tells you the truth and not telling you your nute solution has a pH of 6.5 when in fact it is 5.5...

so couldn't you just use distilled water? isn't distilled water supposed to be at 7.0, instead of having to purchase those calibration liquids?

edit: oh ok nevermind, soil and nutrient testers are differen
thanks for the help, hopefully I can get this plant at right ph in time

oh yea, sorry i forgot u had distilled water too, i think it should do the job (someone else's opinion could b useful here, or maybe theres already a post about this here?). Didn't mean to confuse you with all this calibration fluid stuff :puppydoge

I got it anyway just incase, that hydro store is out of stock on those meters, they're backordered until end of week, should I just water with regular water until I can get those testers, don't want the plant to get worst, but somebody also mentioned, don't know if it was on this site or not, that I might not be giving it enough nutrients since I only add nutrients once a week, since ocean forest is pretty strong as it is.

Is this a science project or growing weed?



Your plants are not that bad looking. Don't over doctor your plants. Give them a week or two. If the problem continues, then vary what you feed, ph, and time you water.See what YOUR plants like. Not what other people plants need. Spray with neem oil to help with any brown spots. Add a little mg to water.

They will still produce outstanding buds.


Don't over doctor and chill......

I really don't think I'm "over doctoring", plants are getting worst by day, not better, I've seen pictures of peoples plants, with all 100% green leaves, and I've posted this same thread on 2 different sites, I believe I recognize your screen-name from hg42*, I posted on that board and this board, and overall everybody agrees it's a pH problem, what's wrong with fixing it before it gets worst? I've already started adding epsom salt to waterings, as suggested from both sites. I'm a first timer, and personally if somebody thinks I'm over doctoring, then it makes me feel I'm on the right track, so don't think anything I said to you was offensive, I'm glad that I'm trying to fix any issues that might occur in the future. When I take pictures of plants it seems they look better on camera than reality, so in the pictures they might not look that bad.

what's this oil that you're talking about? I've never heard of anything like that.
