I stopped buying water i use tap water again fine. it so suspicious coming in with 40 gallons of water lolol and it gets pricey i just leave it in a huge bin for 24 hrs then use it been working fine. I need to get PPM meter for the ucoming hydro grows

That's fine if you have water that you can use. ray's tap water was 500ppm before any nutes. That's more than it should be even if it had nutes in it for the stage he is in. I want to get a good filter before I use mine instead of store water. Not bad at Walmart though 76 cent's a gallon. But I don't have to worry about someone seeing me either. And it's not just the clorine that I don't want. I hear there is something called clorimine or something like that, that is also not to good for them. And my grow closet is right next to the bathroom. And the plumbing is right in the wall by the door. Would be easy to hook up a supply and drain right there. That would be nice. To add running water and a drain to the 40amp electric that I already did. The shit I could grow!!! Wait till you see my grow in another 6 months!! The wife got a full time job now too!!!! I'll have more money to buy my grow stuff!! between that and quiting smoking Cash flow will be much better.

Hey guys Hash lover/ 1982 grower...how your guys doing? i know you are anxious, last night was interesting night to me...this is the results:
i flushed the whole system with destillided water, let run and clean empty the whole thing, i won't go over numbers here because i have another interesting information for you guys . it may be the problem...PAY ATTENTION TO THIS:
after flush and clean the system.
i put destillided (plain)water in my reservoir and the ppm was 0, ph 7.5 ...then
i put ph down fromGH..and put the ph 5.8...NOW ...after put the ph down 5.8 i look the ppm was 350ppm...i was surprise with the result...again i use another galon of destillided water and did the same process in diferent reservoir ..the result was the same.
after that i run the plain water in the system with the plants there and the results was the same water 5.8 , ppm350...now i didn't put any nutes in it. the system is running in plain water, till get your guys conclusion about the situation.
now my question is ...
destillided water comes with ph up and we have to put down?
it is normal the ph down from GH ..increase the ppm of the wate ?
P>S what should i do now?

thanks guys

hey man i had 6 plants exactly like that the tips get crispy and brown and start to curl ...if you dont take care of that ur gunna lose ur plants trust me i lost my crop to that couldnt figure out what it was...????

Rootbound.

not 1 plant was rootbound i recccomed rereading the whole thread. 3 of the plants are over 7ft tall now

my problem was a total nitrogen deficiency, and shitty potting soil.
the soil has to breath very well for pot so get some sunshine #4 or foxfarms

Very interesting ray. No, distilled does not come with ph up. Really no need to ph the distilled for flushing. Having the correct ph means not risking locking out different nutes. It does vary for different nutes, but if the ph is not within a certain range the plant can not take them up. And since there are no nutes in it you don't have to worry about it. The distilled is pn 7'ish because there is nothing in it and is neutral ph. The amount of ph down needed to ajust distilled distilled water should be very little. The more stuff you have in the water the more ph up or down it will take to get it where you want. For how much you should have used your ph should not have been anywhere near 350 ppm. I think most times I use it to ajust after adding nutes it maybe goes up 50 ppm or less. I will try it later with a gal of distilled and report back. How much ph up did you put in the water? Are you sure your meter is right? I would ran plain distilled, with no ph up. Run through once, checking ppm and ph before and after and let us know. If all goes well(you should expect to have some ppm after letting it run since it will pick up at least a little from the system) then add enough to make a seedling mix and let it run for a day. I don't know what that will give you for ppm but if it is over 400 add water to bring it down. Try for 350-400 ppm. Them go from there if it works out and stay where it should. I think you have a problem with the ph down maybe?

man it sounds like the problem was buildup. now its fine. i read what you said and you are now clean. it was buildup on the walls of the tubes. ph down would def count as ppm. just measure your nutes at manufacturers recommendation next and get the reading after. it will be 350 ppm higher because of the ph buffer. your prob is soleved. when you change your res just run freshwater through it for an hour or so. sweet!!

his might take more buffer because his water is 7.5. my water is 6.3 out of the tap so requires less buffer. but since pure water is 7 then there is already ppms in there before i add the buffer. 350 sounds fine for ppms to me if he is bring down from 7.5. if your water is 7.5 to begin with than there is already something in there and therefore ppms. i'm pretty sure only water with ph of 7 can have 0 ppms. 7 being neutral. either way i think your prob is solved. good luck man.

I was going to check it with mine but don't have any distilled to do it. It would not be the same if I did it with anything else. I need to get more tomorrow anyway. So I'll do it then. I didn't have a ppm meter the last time I ph'ed plain water. But it seems like I used very little buffer to change it. And when I use it to change my ph from 4.8 to 5.6 or so with nutes it only brings my ppm up about 30-50 ppm at the most.

thats strange. must be diff nutes. i just use a 2 part veg and 2 part flower but my ppms are suggested at over 1000. i i were him i would just mix as per directions. i dont know. good luck.

allright i decided to look into this. unless 7ph pure water it cant be 0 ppms. average buffer takes over 100 ppms to bring down ph 1 full #. your 350 tppms from 7.5 to 5.8 is fine. search google. its a polular topic apperently. but you are fine. or search google. seeya

I was using the same ones that he has. I certainly could be wrong that it took 350 to make the adjustment being plain water. The hydro nutes also have buffers in them too. When using the GH nutes like the directions said, a lot of times I didn't have to adjust it at all. The ph would be in the range.

this is a complicated subject. lol. after you do all that what are your ppms? gotta be at least 600?

i think you dont water them enough roots can grow level with the soil. the key idea is having the dirt moist enough that your finger dont get wet. the key idea is using the right amount of water to moisten all the dirt so oxygen can penatrate the soil water stressing is fine if you want tall skinny plants. vitimin b1 or hormones at walmart should be used with every other watering. this works for me when im using any sise planter. plants may need more water during budding. high phosphorus bad shit does the trick.

what the? were talikin soil? sorry man. hey reefermaster. lol

Most times when I mixed gh stuff was before I had a meter so I don't know what the ppm was. But I did have a good ph meter though. I went back to AN nutes just a little while ago. Mixing wise they are about the same. They are both the 3 part that you use for the life of the plant with different mixes. I like to be able to have the option to adjust the N-P-K ratio myself. But most times go with something that is at least close to what the program suggest's. Ya, With all the different nutes and mixing them can get complicated if you want it to be. But that is the way I like it.

Hey ray here's a good pic of putting plastic over the ebb and flow. Post # 485.https://www.rollitup.org/hydroponics-aeroponics/112167-hydroponics-question-answer-newgrowth-style-49.html

Ok got some distilled today. Someone must be growing weed around here too. Seems like lately when I go to buy water it's almost gone. Only been able to get 5 gal each time. Can't wait to get a filter. So I took a gallon of distilled, checked ph and was 7.5. Calibrated my meter to be sure. Actually just tasted it and it was right on 7.0. Checked ppm and read 0. Then I added about an 1/8 tsp of GH ph down. Checked and ph went to 3.6. It does not take much to change the ph in distilled or RO water. Checked ppm and it was 58. So ray if you ph your distilled water to 5.8 your ppm should be less than that. I don't remember what you use to adjust but I will go back and look. What ever you are using should not be 350 ppm. Maybe it's just that bottle but I dought it. But what ever it is, you are wasting a lot of ppm on that stuff.

LOLOLz i think the same shit when i used to buy distilled there would only be like 10 jugs left sometimes. i would be like someone else is growing.
