just keep an eye on em. did you ever get Super thrive? that would be a must for me with my plants looking like that.. If they start getting worse... flush again and keep it on ST only 1/4 tsp per gallon until they seem to be almost 100%better. I still think they are too young for nutes. good luck.
Congratulations on your 1st of many hydro attempts.
I hope all goes well for you clayboy.
At first I thought you were over watering. My plants looked similar when I did an NFT system some time ago. I think the yellowing was closely related to the roots being starved of oxygen in my case. I was over watering and drowning the roots.
I'm not sure what the problems are with your plant. Glad people are on board giving you a helping hand. I'm going to read this thread again and probably ask a few questions.
Did you plant your seedlings in any other medium beside clay i.e a rockwool cube?
Did you steralise/wash your clay before use?
I see your system drips from the top. Is there an air supply in the bucket?
Your pics for june 3rd look like over fert of some kind and over water, but that is my guess.
Is there an air stone in your reservoir that holds your nute solution? if your solution is left still for too long then you could have a build up of nutes getting dumped onto your roots.
I recommend flushing with pH balance water pH 5.8 for 3 days and cleaning out your reservoir before hand. Then I'd commence 1/3rd strength nutes..
I'd want to see some sign of recovery before piling on more plant food. But that is just what I'd do and isn't a textbook suggestion.
I wouldn't drip constantly without prior practice. I was planning on flooding my current grow 24/7, but I'll leave that till I've had practice. Hydro is quite unforgiving and doesn't allow for many mistakes. I'd maybe drip on max 10 times per day giving the roots oxygen inbetween. My current grow is similar in so far as I'm also using clay media. My top inch of balls aren't low enough to get wet, so keeping the balls mosit is not that relevant. Feeding the roots/plant is whats required, the balls can dry up, its the plant that needs attention.
Very best of luck Clayboy, and I hope you can answer a few of my queries!!
I ordered some superthrive this weekend, I'll try that and I ordered some clearex to flush withQuote:

-My next plan of action is a flush with clearex, then plain water with superthrive only to see how it recovers. Thanks for the help!
they don't look like they are doin all that bad to me...do you have a meter? mine looked like that but seemed to perk up a bit when I upped the nutes
if I'm right they should be kinda stiff only other thing it could be is over nuting but if yer between 250 and 400ppm you should be fine
I'd say you can get your ph atleast down to 5.5 without any trouble and I keep mine even lower at times
how much food are ya adding?
Good luck mate, I think you are already taking appropriate steps in relation to the answers u provided...
alright, I gave her a really good flush tonight with clearex, added fresh water only with 1/4 tsp. superthrive per gallon. Let's see how she does.
you go boy, hit the regement and she'll love you, pics?Quote:
