PH question

[420KushMaster]

i use bio bizz for my organic soil . bio bizz works awesome and worth the money

like you said you are getting floaties in the water and that is where nasties will collect and cause you much problems. try using a hydro only nute system that is will desovle better into the water it will be easier for your first run. good luck

it should work if the roots are not to bad but it will stress out the plant and take a while for them to recover if done right.

Your fertillizer has to be complete with all nutrients since this is hydro. If your ferts were intended for soil/soilless growing, they probably lack enough calcium and magnesium (this is not a rule). Calcium = good root growth. General hydro floranova series is excellent to try. It has 1 bottle of grow and 1 bottle of bloom. You do not have to add any suppliments to this. The flora series requires 3 bottles: micro, bloom, and grow. It also does not require suppliments.



Once you get some experience using storebought ferts., you might want to venture into creating your own special recipe. See how to make your own nutrient solution in my signature below.

I am wondering if we can be a bit creative. think it might be possible to just cut the veg on the plant/clone back some and just chop the roots redip it in rooting solution and then put it in a dome until new roots come back. And get new nutes for the rez in the meantime?

If you're dealing with pythium or other serious root infections, your best bet is to get rid of all the plants that have been in contact with that same reservoir. Your res, netcups, all the tubing and anything else (such as your heater) which has been in that solution needs to be completely washed down and sterilized. Replace the airstones with new ones. Dont bother trying to save any of the plants from this current res., even if they appear to be ok, because they can be carriers of the disease and spread it later on to other healthy uninfected plants. Pythium acts like a systemic disease in plants, it has been known to show up in what seemed like healthy rooted cuttings taken from infected plants.

Start now by taking everything apart and washing it down thoroughly with warm water and household bleach. Soak all the parts you've already cleaned in more bleach & water. soak the rocks in a strong peroxide solution, (not just the 3% drug store crap), or better yet...boil all the grow rocks to make sure all the pathogens have been destroyed. Ignoring any of these precautions will only cause you to have a repeat pythium infection in your new replacement plants. Sterilize any other water holding tubs you have while you're at it.

I will go this weekend and buy some new clones and nutes and then get back with you to make sure I have this thing setup right.

shopping suggestions...
For begining hydro, I suggest going with the general hydroponics flora series nutes. I also suggest resisting the temptation to add other bud boosters and other assorted concoctions to the first time hydro users grows. Its very tempting I know, but really not a necessity for producing damn good buds in hydro. Many many growers have done fantastic jobs growing with only the basic hydro chems...gh flora, pH down and a pinch or two of plain jane epsom salts. Many sucessful hydro growers don't use much of anything else in fact.


So heres the suggested shopping list for now...
Get one pint grow, one quart micro and one quart bloom.
Also get some gh pH down. The liquid is the easier than the powder to work with and it is not just some sodium based aquarium crap...it's phosphoric acid.
You already have a tds (ec) pen or meter ? (you did mention a measured ec)
The ph liquid kits like you have are ok, but a decent ph pen / thermometer combo would be very handy. A cheap 2 dollar floating aquarium thermometer like they sell at wallymart is also suggested.

As far as the size of the cubes I have no control over that currently. I only know of 1 club that sells clones and all the clones are in cubes that size.

Well you could carefully strip away as much of the cubes as possible without harming the roots. It's fairly easy, just pull the rockwool away starting from the corners, peeling it down and away from the cube and roots like peeling string cheese. Leave only the rw near the center of the rootball if it looks like the roots would be damaged in the process. The smaller or less rw in the netcup full of rocks the better imnsho and ime.

Your not seeing the aeration currently in that pic is becauase of how the tubes run down, when we lift the lid the air stones come out of the water. There are 6 airstones.

Yea that explains why theres no bubbling in the picture. But still, I suggest not using those little tiny stones, but instead using the large 10 to 12 inch long bars. Four or more big bars with large capacity pumps double outlet driving them. AF uses one double outlet pump for every 12 inch stone bar. It's always better to have more bubbling action than risk not having enough. Not having enough aeration is just as bad as having a res thats running too warm. <-dont overlook that important point.

One last question growing...
Are you or do you know "ISAG" ? :jawdrop:

hiya growin,
sry you have to start over but like you said, maybe you can save your plants by taking cuttins off them.

Try cutting off the top shoot on evry plant and turn them into clones. Use a scalpel, not scissors, read up on taking cuttings if you are unsure, lots of methods to use.

Hope you can save the plants.

Ps: the plants are going to die soon, they look like they are dying already so don't wait too long.

btw growing... when you go to get your new batch of clones.
Stick with only one strain of clones for your first grow. It will make everything much easier later on since with clones of one strain (hopefully all from the same mother) will grow more evenly height wise and you will have a more level and even canopy later on when the plants are flowering.

Said another way...
Growing several different strains like you tried above, will only make everything more difficult to manage in your grow from all the uneven growth height.

rez question

rez question

Well I was able to save two of them. I do have a question though. I got the general hydro nutes, and got more pumps to increase the airflow. The question I have is with the setup I am using do I really have to completely replace all 15 gallons of water every 10 days. Or can I just fill up the rez with freshwater back to the original level. So I would be adding only a few more gallons of water each week. Or is it just required to replace all the water every 10 days?

I think that what happened was a direct result of the fish emulsion fert. Once I cleaned the plants and soaked them good with a clearing solution the roots looked alot whiter and most of the "sludge" washed right off. The ph is staying alot more stable with the gh nutes. I am also using the gh ph up and down.
