leaf disorder

Hello
That s my first time grow (rdwc indoor).
This is my system ( please see the pictures)
nutrrient : Canna Aqua
room temperature : 78~80
water temperature : 69~72
is there any problem, please let me know! thank you.

here have a problem that the leaves are very strange. is this cause by TMV? if it is , what should i do to fix it?
Looking forward the reply!
thank you very much!

I wish I had that kind of setup when I first started growing. 0_o

Hello mate, first of all I would like to complement you on your set up, it's very well designed and obviously you have invested quiet a bit of money. Personally I would always recommend for beginner to start as simple way as possible, professional set up requires a professional knowledge.
To find what is the problem I need more info.
1. Strains (auto or photo period?)
2. Apart of canna aqua what else do you use?
3. How do you cool your water?
4. What do you use for pH regulation?
5. Did you soak your clay pebbles in pH'ed water for 24 hours?

Give as much info as possible, every little thing is matter.

i am so glad to hear from you.
1, photo period seed
2. I have putted canna aqua, RHIZO TONIC, CANNA ZYM (Light feeding) and RO water at the start(about a week ago). and than, I have putted Hydroguard today.
(total EC 0.9, PH 5.5)
3. I have a watrer chiller.the temperature is between 69 and 71.
4. I am using a regulator(liquid) which is special for plants.
5. yes i did (about 48 hours)

Humidity 55%~65%

Thank you so much!

Yep very nice set up. My 2 cts. The one picture of seedling looks good, the others no so, but could just be bad seed/seedling.
Nutrient level is high for plants this small. I usually run my PH in 6-6.3 range for small seedlings and starts and lower to a low of 5.5 as the plant matures. All else looks good

Add one more question that I have this strange leaf one only at about four days ago, others are getting strange since yesterday.
About three days ago, I have experienced seed stage changed into veg. stage so i have putted more nutrient as the information showed, after that action the PH of water was falling down to 4.3 so that i have to putted " PH up" to let PH up to 5.4.
One more, I don t have air pump in water tank so that the water just stay in normal temperture. Is this goning to be a problem to worried? (water quality is fresh or not)

Thank you!!!

Thank you for your advice, I would try to up the PH.
what should i do now? should i take out of the bad plant or keep it? if i am keeping it , is it can infect to other healthy plants?

If one is infected they probably all are, you can try and save them. You need aeration and circulation in all tanks.

The problem created by all this additives and other unnecessary stuff that you are adding, Rhizotonic is partially organic, cannazym is also partially organic enzymes and that hydroguard is a beneficial bacteria. When growing RDWC there should be no living organisms or any organic matter in the reservoir at all. All you need is canna aqua some calcium and magnesium additives (plant magic magne/cal will do perfect) For pH use liquid silicon(pH up) or phosphoric acid (pH down). That is all you need for vegetative period. For flowering you will need to add PK 13/14 and canna boost accelerator (optional as this stuff very expansive)
Also adding a water pump is important the whole reason of RDWC is for water to constantly move, as it makes harder for algae to appear and reducing reservoir temp to 20c will help for this purpose.
I would also recommend to use tap water, as RO water will lead to pH fluctuation.
And yes 0.9 EC probably a little to much for their size!
Everything else looks perfect. Very impressed with your set up)

and about pH canna recommend 5.2 to 6.2 but the rule of thumb is always 5.8
