Sick california orange bud

Maybe I can provide a new perspective here...I may have missed it but did you get an EC meter yet? If not you will just have to go through trial and error with each problem you have and that is a Pain!! I know you know that already Just kidding bro

I absolutely do not think you have iron issues. Iron def turns leaves an even pale green "whitish" color. You are experiencing intervienal chlorosis that is a symptom of many problems but not Iron def. I absolutely do not think you have an over fert issue. You would be burning leaf tips more. I absolutely do not think heat is a problem. Intervienal chlorosis is not a result of heat.

I had a similar problem where my city water comes out at 36 ppm(EC meter)
I had to add Cal-Mag at 200 ppm to resolve the issue. Some of your leaves will become necrotic and brown and die if this is left untreated and some of the yellowing will green up again when it is resolved. Iron is also in cal-mag.

Don't start messing with peroxide unless you have serious root rot. The peroxide will kill beneficial microbes as well as killing the bacteria. With your lack of experience I could see more mysterious problems arise if you mess with peroxide. Just bubble your nutes and you will be fine on oxygenated solution. The oxygen will help the beneficial microbes to grow too...

Good luck -Jay

hi!
Just wanted to quickly drop by to say that sproutco's receipe (end of page1) is working! Plants have recovered nicely and allmost all new growth looks absolutely healthy. I have to admit that I was more than sceptical, but you sir are a miracleworker perhaps Ata-clean and rootjuice (mentioned at last page) helped too.
Im planning to stay on that mixture for some time more. Perhaps more grow/nitrogen in the future before flowering phase. Not sure yet.
Im in a hurry so pictures coming later. Once again, big thanks to sproutco and others for comments and sharing their knowledge.
