Hi, Currently on my 3rd week of veg. Had some problems in the begining and thought I fixed it but now the leaves look like they have nute burn. Anyone know what this is?
Also when I measure my PPM and PH I put the pen right into the resevoir. Is that correct? Because when I put it in just the cap of the PH pen it reads totally different.
My PPM right now is 645; my PH is 5.6 and my water temp. is 70.5
Any help would be great thank you.
Is it just the bottom leaves that are getting the weird spots on them?
And a little tip burn is ok, that just means you know that she's taking as much as she can. A lot of people run their grows a little tine bit hot just so they know they are pumping her full of nutes

It was just the bottom leaves. Now it's on the ones towArds the middle also
fill out the trouble shooting form (can be found in plant problem area) and post here so we can help. need more info than just ph, ppm and temp. like what nutes are you using and grow media and such. Almost looks like a Mag def but I dont want to guess.

Did you pre-soak your media in pH corrected solution? yes
I am seeing the spots on mine also. only on the northernberry but not the skunkberry?? week one of flower after 4 wks veg.
am also using GH 3 part, on hydroton pellets and after adding Mg. thinking it was that, not!
so now I think its a K lockout, due to not carfull mixing of nuits. all three parts need diluted into a volume of plain water before combining them in the right order. if after this last drain and refill(today) this doesn't solve it I am clueless
unless the formula on the bottle just doesnt supply enough K
I will be watching this thread also

been using GH 3-part for year and a half and have never had spots like those. Nute mix i use is 5/5/5 (ml per gal of micro-grow-bloom mixed in that order in a gal water jug) during veg, half that for newly rooted clones, and 1 drp ST per gal. First 2 weeks of flower change to 5/2.5/10 and do not use ST during flower. starting 3rd week change to 5/0/10 until 2 weeks before harvest. at that point go 2.5/0/5 for 1 week and then 1 week of plain PH water. PH runs about 5.8 during entire grow.
ph and tds meters go directly into the water.have u inspected for bugs?
Ya I checked for bugs and there aren't any... Do u think i need to add some more cal-mag?? The leaves have goldish, copperish type of spots on them
Just some advise. I tried many different ways to grow and the bubble buckets and the aero setups /w the clay is a pita if your not spot on with nutes. IMO I believe you have a nute problem. Best thing to do is change the resivior(new nutes 1/2 strength). I like big resiviors. This helps with plants not making sudden changes... With 1/2 strength nutes you can always kick it up if they are growing slowly. As the plant uses the nutes and evap happens your nute solution will get stronger (not good if your dosing full strength on mfg lable). Also topping the resivior with fresh ro is very important.The #1 reason i don't like these setups is you have to contantly check these till you get spot on. I would advise a larger resivior cause its easier to keep the nutes at the right level for longer than 2-3 days. I would get away from the buckes and go to cocomix just my opinion. Good Luck.
Ya this is my first grow with these buckets and im going to change to the waterfarm individual buckets. 8 of them. Anyways I took some more pictures. Im going to start flowering sometime this week.
Hi all!!! :thumbsup:
I think you have a PH problem.
I am not a big hydro grower, I only grow 1 plant hydro.
I disagree with PhatOptimo on the bucket though. :D
I use a pump and spray system in 5gal bucket.
I never check PPM. just use Fox Farm Nutes and CalMag, I use recommended amounts of liquids and 1/2 str. dry nutes. I only PH the nute to 6.0 and let her go. I use about 3Gal. week, lately I add water on day 5 if pump starts sucking air. I use a rinky-dink time with 5 min. on 15 min. off.
I would probably do better if I had a good system, but the bucket works pretty good and is real easy.
Good Luck :thumbsup:
My ph is regularly checked and it's between 5.4 and 5.7
well just from the pics it looks like ph spotting and mag deff,your magnese might be adding to the funky brown spotting.
could you elaborate a little on Ph spotting,whats the cause? rapid swing, too high, to low ??
I adjust daily if ness. try for 5.8
also fed more CaMg than usual, and no noticable benifit
this has really got me banging my head
ph spotting g is the plants first attempt to let u know there is a problem,it can look like small yellow and brown sploches showing up in various places,it is then usually acompanied by minor leave twisting and then the usual fringe patterns around the leaf edges,.i am auctually battling this verry problem my self,my hydroten didnt soak long enough and keeps getting maddddd ph creep,
now we are getting some where! I had soaked the hydroton (as usual) but had to put it into use before the 4 days normal soak time at Ph 5.4 .
is it posibable that this is the problem?? upward drifting Ph
if so what did that do lock out the Mg?
the problem with ph being to high and low is that it makes the plants basic living elements unavailable,its kinda like being stuck in the desert with out water,your still alive but are dehydrated and sick.different ph levels lock out different micro nutes and metals that are normaly available.i have to add a gallon cap of ph down every day in order to stay at a between 5.5-6. it will creep up to a cool 7 with 6 waterings per day at 15 min intervuls,and i only use hydroten and one rapid rooter to get em started.
I agree with Daddynobucks keep the ph at 5.8 not 5.4 too low. I am in DWC with lots of airstones water at 68 and have no spots at all. Green as can be. I switched to House and Garden from GH and love it so far.
Sir...It is time to flush. Give it a week of flush, and then add nutes again. You keep treating problems, and not allowing sufficient time for the plant to adjust and let you know that you fixed the issue.
Your PH level is waaaaay to low for these girls. Your PPM is good for veg (but the new grow is rather light)...This makes me concerned for your overall PH stability due to the fluctuations. This will cause the plants to get the copper spots...yellowing and burnt tips etc.
To put it bluntly, you are suffering from lockout. Flush your res...give it a 3 days to one week of flush...and then add new water and nutes. Instead of looking for an explanation, you should be eliminating the variables.
Good luck...and I am sure they will come out of this funk! :jointsmile:
Yup. the PH was waayyy too low. Just did a water change and am going to start flowering. Wish me luck. I adjusted the PH which is now at 5.7
they have been on plain water 5.8 Ph for a week now, today the 40 gal rez. was drained and rinsed, then a fresh nuit. mix was made. but switched to pure blend pro Bloom and CaMg mix at an EC 1.25,about 1/2 strength at 5.8
I'll keep ya all posted
Daddy
No problems anymore. Got the ph at 5.7 and the ppm is at 840... Water temp at 70... I'll take pictures tomorrow.
you said PH was way to low, what was it at??
It was at 4.3 I don't know how it got that low...
well did u soak your hydroten? thats usually what causes maddd ph flux.check every day to make sure its not happening again. i check in the morning and at night as well as checking the ppm once per day.since your in dwc if u keep your ph right the hydroten will soak up that ph number much faster than other systems.ive been battling this flux for almost a month with a top feed drip.what a pain in the ass.
