I checked the roots and they perfectly white. I run a chilled res and use a Root Tonic with every feeding up till week 4 of flower.

Hello, here are two photos of the same grow, same system. Two of the plants have nutrient lockout and two are healthy as can be. I've included one photo of each. the top photo is a Erkel and the bottom photo is Zod. The Zod is locked out and the Erkel is doing great. My tds is 620 (500...

I'm not super familiar with a flood and drain system. But, I don't think you need air stones. I use air stones in RDWC where the roots are constantly submersed in nute water and would not otherwise receive oxygen. I think your roots will get aerated during the drain cycle.

I've been reading all I can on Rock Nutrients but can't seem to find anything on mixing order of my nutrient solution. I'm running Rock using a 2 site, 33 gallon RDWC system and RO water and have been for about a year now. I have been seeing some nutrient lock out showing up in clawed fan...

Thanks HydroRed. I didn't think to check Hydorzeme's website.

Im using a RDWC 50 gal. system, chilled and attempting sterile for the 1st time. Didn't have much luck with bennies. I've been searching around and can't find a good recipe, other than the bottle, for H202 and Hydrozyme. I'm mostly wondering if H202 will kill the enzymes? What dosage in...

Tyke1973, How long did this take to finish once you switched to 12/12?

You could use distilled water from the grocery store. but you will have to add cal-mag because distilled water has 0 base minerals. Add the cal-mag to the water first at 25 - 50% of the recommended low does and then add the other nutrients at the same 25-50% ratio for you seedling. You can...

You can also buy RO water from an ice house or grocery store

That's high for tap water. That means there are already a lot of ? Minerals in your water. I use a tall boy garden filter with an reverse osmosis attachment. http://hydrobuilder.com/tall-boy-de-chlorinator-sediment-filter.html?dzid=csegps_HL31050&gclid=CMKa-PiDrs4CFReUfgodUSANPA RO water has...

For a plant that size you only need an ec of 0.3 or so. I'm not familiar with your setup, but in DWC I add the nutes slowly...over a couple of days....built up to my target ec. watch the plant for changes after you feed it. This feeding schedule might help you out with where your ppms should...

What's your ec at? Or ppm? Yellowing looks like N deficiency

They are tall and stretchy. Here's a photo of the whole plant. It's about 7' tall at week 3

Photo links are broken. And Growfaq link is not working from page 1 of this thread.
