Hydro Problem- cant diagnose

Hydroton or coco pad. The Hydroton is reusable, just wash the dust off it first.

You really shouldnt be having this problem. Is there any light getting to the roots through the netpots? Maybe cover those.

Roots need to breathe so maybe backing off and letting them absorb some oxygen will help too.

no light getting to the roots, something tells me that its a problem with my water source, Im on a well, is there any way to test the water for deficiences? My ppm read 100 for water with no nutes. I only run a 15 gallon tank for two tables perhaps I should run 40 gallon rez? Is an airstone likely to help?

i think 600 ppm may have been the problem. mine are like 18" tall and atleast 12" wide & I just took them from 500 to 600 ppm today

also I suggest to forget all that flood and drain jazz and just put the plants in the tops of the water tank and put an air stone in there. no reason to complicate your life.

How would I mix the nutes into the tables without coming into direct contact with roots?

Even at 260ppm the PH continued to rise to over 6.8 in 12 hours, everything I've tried has not been able to keep ph at a reasonable level

whats the ph of your water from the tap and also if you leave tap water out and test it later do the ppm's slowly rise?

if not then we confirm its due to your nutes that the ph is rising and your water is fine.


what brand nutes do you use? and whats the dosege you give them per gallon

From what I understand you can take a sample and mail it to a lab and get an analyses of your well water. I think the number is 70 ppm of calcium where problems start to occur. What I would do is go buy a couple 5 gallon containers and fill them somewhere they sell water for like $1.50 each and try that for two weeks. Then you will know for sure.

Yes, a larger res is easer to stabilize pH in. Yes airstones will help also.

PH from the tap is 6.6, ppm as I mentioned is hovering between 100-115ppm, I will let sit and advise if ppm rises or not.

Healthy Harvest is the Brand Name I use, it is local to my area. Here is an exact breakdown of dosage per gallon.

Grow - 10ml
Bloom - 10ml
Micro - 5ml
B1 - 5ml
Cal-Plus - 5ml

The above is for Veg only of course, and it works fine for soil operations, I'm beginning to believe that it is much too strong for early veg with a hydro system, the recipe was provided from local grow store where I purchased nutes.

FYI, today was the first day I've been able to stabalize PH (not have to adjust) in over two weeks. PPM are at 360 in rez currently.

Any suggestions for different nutes? At this point I'll try anything.

Well yea I think your right, soil nutrient levels are not the same as hydro. The micro nutrients are different too. It looks like you are used to a three part system you may want to try the largest hydroponic nutrient manufacture. General Hydroponics

They have a hard water Micro that should work for you.

Heres a link to a site I get a lot of stuff from. Greentrees

Oh and I would stop the B1 right away.

Well water will do some crazy shit and you are def having a prob w/water if you have used this sys before. As Cruz said GH Hardwater micro will cure that but use with caution I use 20% HWMicro to 80% Reg and it will hold PH in range. Sometimes I get cheap and add back water and more nutes to delay a res change but never use mor HW micro. Just a thought have you considered a R/O system? Thats the route I ended up taking and has saved me alot of headaches. Well water properties can change by weather the enviroment whatever. A ro would eliminate all Probs with water. The only thing I have to add extra is a little epson salt for Mag. Good Luck

Loco brought up a good point. Although GH nutrients work fine you may want to pick up some calmag. Now he suguested epsom salts but calmag does a better job and its measured and ph ballanced. Once you get used to hydro then yea maybe use epsom salts but if you are not used to it you can harm your crop.

use what u got as the lucas formula
8ml micro and 16 ml bloom
u should not need that other stuff
but it is meant for RO water

i use the gh nutes too and i dont even ph my water or even test it anymore,


gh nutes always hooked my ph up perfectly so its one less thing to worry about

When I saw that I thot either nute burn or overwater (underoxygen) or ph. Gh wont need cal mag. The flora nova is supposed to be full proof. Cal mag def looks way dif, like spots first I think I usually noticed.

so what do you think about my nutes regiman im trying it for the first time:

(normally i only use 3 part flora series)


GH 3 flora Series nutes throughout the grow
adding koolbloom lquid from start of flower production
switch to kool bloom powder for the last 4 weeks of flowering
add Gravity 3 weeks before harvest
leech with clearex 5 days before chop

I dont think you should use koolbloom so early. Not till the 4th week of flower. also if you do use gravity be sure you have a low nute load. less then half.

Otherwise sounds good to me. 24hr with clearex worked great for me last grow. I went 10 days though.

you guys ever read the whole lucas thread? About half way thru they discover that what they call N loading gets them more killer yeilds. It is when up until flower you feed the veg formula then when the flip to 12 ans 12 comes you start adding flower formula in with the addbacks. I guess that gets you killer results.

whats addbacks?



i switch them to 12/12 then give them equal parts of bloom micro and gro then after about 1-2 weeks i switch to 123 formula 1G 2M 3B then maybe a week after that i add liquid koolbloom to the mix, so this time i will also add gravity and kb powder


you guys use gravity? how much and for how long should i put it in my DWC setup?

Could let your water sit in tubs for a few days before adding to your res. and before adding nutes...... i had a similar ph problem and it was because i was adding Powdered ph down every 12 hours, i switched to the liquid ph down kind and had immediate success. Make sure your water tempis below 70 in your TABLE and it is equipped with airstones! your babies could be locking out your nutes due to stress aswell (heat, ph)

have not had PH problems in 48 hours, i believe problems were a result of over nutes. I am currently running 330ppm with minor improvements showing. I hope the damage is reversable? Should I run water constanly (with airstone) or is it better too water for 15 min with 1 hour downtime?
