So, an interesting side note: I was checking which of the 24 tubs I wanted to tear the plants out of first and I started looking at the roots of the worst of the lot. To my surprise, they looked really good. Excellent really. Bright white, bi-fricating really searching. Quite surprising...

Restart with clones from mothers. If that doesn't work, a cup of gasoline and a pile of current culture stuff. Then I'm growing in dirt. RDWC nothing but problems. Some mine, but a big drawback I have found with this system is the size of the epicenter. This should be a very large tub...

PPM now 130 just tap water and ZeroTol (h2o2). Plants still doing nothing. I called Current Culture and Dan told me he thought the plants were shocked very early in their life, and they are now no more alive than cut flowers. Can anyone else verify if this is true? Can the plants just go...

My roots got too long coming out of the EZ-cloner, so I coiled them up at the bottom of the netpots in my Current culture RDWC 24-site unit, then covered them with Hydroton. The rootballs would have sat too high in the netpot otherwise, I would have planted on a few inches of Hydroton per...

I agree on the micro part, but if you read the label on Protekt it says to add it first (even before micro). I've been told that you must also adjust the ph below 7 before adding ANY nutes, then do a final ph check once finished adding all nutes and mixing. Also, remember to dilute ph down or...

Superstoner1: What do you mean "Never on H2O2"?

What is the correct order of nutrients: I'm using Protekt, and Advanced Nutrients 3-part with straight tap water. Is it Protekt first / then h2o2 / then nutes, or does the h2o2 need to go first/last? Using rdwc

I'm glad you brought that up about adding silica. I'm adding ProTekt (which raises PH) after I ph down straight water to about 6.2 or so. I know it says to add this before any other nutes, but I'm wondering why this needs to be first? In the past I've forgotten to add it first and added it...

Getting better. Your suggestion seems to be making a big difference...KUDOS! They're more vibrant and clearly happier. I can't believe I've even had success in the past while not doing this. Shows how adaptive plants are.

Right, I agree less should be used that what is suggested. But that wasn't what I meant. What I want to know is if I should be using EQUAL parts of EACH of the three while I'm in veg. Bottles say yes, their own feeding chart says no. What gives?

On the bottles, 3-part Advanced Nutrients say to use equal parts grow, micro, and bloom in veg. But if you look at their feeding charts, they give very different numbers. In my case, I have a 240 gallon RDWC and of micro and grow, I'm supposed to take 28 fl oz of each. But on the feed chart...

GK1- Beautiful post, my friend. Thank you so much for taking the time to write all that. Information everyone should know. I wonder if you could then confirm 2 other great pieces of general knowledge? See 2 attached files:

I am adding ph up, but I do that after I mix all nutes in res. Should I be adding ph before nutes? When I add ph, do I need to dilute it in water first - and then add? Or can I pour into res tank directly from bottle? I check levels several times a day, which is why I can't seem to figure...

Nutes only at 500 ppm. Is this too hot for DWC? Is there something special about AN, or would 500 ppm be too hot for all brands of nutes?

What would plants with too much Cal/Mg look like? Would the leaf tips be burnt? Would the sides of the leaves curl downward? A pict would help a lot. Lots of deficiency picts out there. Does it look similar to a deficiency? What are the characteristics of too much Cal and/or Mg? I'm using...

Even when using RO water? I just did a nute change, so I'd rather not have to dump the new res liquid. Would pumping half into another container, then refilling with fresh RO water take care of it? I'm using Advanced nutes 3-part.
