please give advice

these are the things that are involved

ph-6.7
nut- 800 ppm bluelab Truncheon meter
growing medium- hydrotron clay pelots
hydro systme using- multi ebb-flow 24 bucket
lightng- 1000 hid 16 on 8 off
feeding cycle 4 time a day during light time

Some krinkles, eh? hmmmm....

Well if your pH is 6.7 i would suspect that one of the micronutrients isn't available....
Try lowering your pH to 6.0 and see if your problems get better....
This leaf krinkle is a very distinctive morphological expression so i am sure some kind
soul will recognize it and tell you which micronutrient isn't being absorbed.....

Maybe Iron or Zinc? Which brand of nutrients are you using?

Hope we get this one nailed......Mr Krinkle indeed......

:ying: guineapig is your friend :ying:

I'll tell yeah straight off, you're pHis WAY to high... using a hydro ebb flow it should be kept between 5.5 - 6.0 . Try lowering it to 5.5, then let it rise on it's own to around 6.0 . Should help.... Hope so :wink:

Whoah, your PH is high. Drop that to between 5.6 - 6.0 and your plants should recover. If the PH is that high, your plant doesnt have access to a few nutrients.

No offense, but how do people set up decent hydro systems which they obviously had to research, and nutrient mixes which they had to research as well, only to not know what their PH should be? .....

In hydro, if you cannot control your PH, you should be growing in soil. Controling your PH is more important then feeding your plant because if it's not correct, your plant won't have access to the food anyway.
 
I second all that.... and would also venture to add that PH is equally important in soil!
It may be true that soil is more forgiving, and you can get away with more... but that doesn't change the fact that excellent results are dependant upon proper PH. Don't go past 6.1 pea. You'll notice on your flora nova bottle that even they don't condone PH levels avove 6.5.... that's the MAX they instruct. Good luck,
Cap'n

I think you got the info you needed above on pH .. so I'll just leave a Flora Line Chart in case you don't have it..It's at least a good reference or guideline.. :wave:


per 4 liters or 1 gal..(3.785 L= 1 Gal)

In my opinion its very hard to tell. Even so the PH is high, its not that high.... 6.7 is high, but i have seen muuuuuch worse. between 5.5 and 6.5 its acceptable, 6.7 its just passed acceptable.

I think your plants are having some other problem.

Did you washed the Hydroton before you used it??
Somehow and somewhat is causing a nute lock. Like the first picture shows a lack of N. but the second one dosnt shows that, but something else.

Im not sure what the problem is... But im preatty sure you have a nute lock up... the plants arnt getting the nutes they need. Maybe something else in the water, like chlorine, or too much calcium, or something.


OR are you sure the roots are getting enough water?? the buckets get well filled?... just wondering



ALSO how are you feeding your plants? the nutes- are you using the Lucas formula, or the formula that its in the bottle.

:chin: On that note marimbas,,, i still beleive the pH is way high,, which in turn will make nutes unavailable to the plants,,, but may i ask,, Pea did you mix the nutes properly? meaning, the Micro FIRST,, then grow & bloom,, because that will cuase a lockup of nutes as well,, there's a chemical problem ( not sure of the details LOL ) with mixing the grow or bloom first into the water... so if you mixed it propperly, then the ph is the main issue IMHO.

Peafunk,

I agree with marimbas ,those pictures look similar to some plants that I gave too much nutrients to. I would make sure that you have a resivoir full of water before you pour nutes in it, and make sure they are mixed up really well in the resivior so plants wont get an unwanted overdose. I have had my ph go above 6.7 and didnt see those extreme of problems. You may want to start by just giving your plants some correctly ph balanced water, then slowly reintroduce nutes but at a weaker strength. To little nutes and you will get a smaller harvest, too many and you can ruin your crop.

I hope this is helpful!

Peace,

an i beg to differ with the pH not being that high,, in MOST hydro applications 6.7 is WAY high, execpt for a bio-bucket type grow,,, but this isn't one of those.... just my 2 cents , since i'm currently growing hydro, with nearly the same set up, only difference being i'm in a 4x4 ebb flow tbl, not buckets.

to all i would like to thank for your advice i have basically found out that the ph meter that i was using was not working correctly i had to buy a new one. the conclusion is probably ph reading

check the pen first!!!

check the pen first!!!

hey pea, you might want to invest in a bottle of calibration solution. Get the 7.01 solution. You dip the ph meter in it and adjust your pen to 7.01. If your ph meter isn't calibrated your reading will be incorrect. I check mine everytime I use it.Good luck nursing your ill plants. Do come back and let us know what the ph really was. I think it was way high. Oh yea you mite also want to pick up some ph down as I think you will need that also. Hope this helps....peace

mitsu1 i have an answer to your inquiry the ph level was down to 3.7 was due to the ph showing 7.0, 7.3 7.6 and so on, the thing that i ended up doing is going to my local hydroponic store and the guy tested my meter meter was no good. if i had my recite i could probably send it in to get a new one on the meter warranty but i could not find it ended up buying the meter again this will not happen again

damn ... I never even had a meter/truncheon ....

never known ppm /// only adjusted PH .....

I've grown a few hydro grows now with no apparent need for one... no problems yet...
<fingers crossed>

Peace

any meter (pH, EC/TDS) that isn't calibrated properly is not only useless, but dangerous, since you'll trust it.

I recommend getting the pH 7.01 and pH 4.01 calib. solution, use both for a more precise calibration.
