Can't really tell what this is...

I want to say this is a combination of pH fluctuation (my pH meter has been a little goofy lately) and mag deficiency? Problem is I can't really tell, some of the leaves don't look anything like the guides I've read.

I'm using tap water in a DWC rubbermaid. Advanced Nutrients Micro-Grow-Bloom and some other additives that I haven't gotten to yet except some H2 (humic acid)

I just switched one of my plants into a separate bubble bucket to be a mother while the others grow, and with just plain water in the bucket it seems to be doing just fine.

This is my first hydro grow, but I was having similar problems in soil, though they were usually very healthy up until about halfway through flowering.

Any suggestions guys? I appreciate the help!

What do the roots look like, also the pH and the EC are the other two really important things when it comes to hydro type growing.

The roots look kind of brown, not the pale white they were when they started popping out of the net. I try to keep my pH between 5.8 and 6.3...is that right? And my TDS was no higher than 400 when this picture was taken. Don't have an EC meter, guess I should get one when I replace my pH meter.

Anyone else have any idea what's going on here? They only look worse today :(

root rot seems unlikely in a DWC system, i have 3 airstones in there and a 30-60 gallon pump (18 gallon rubbermaid) so it should be good i'd think...and nute burn at 400 ppm a month in? Seems odd.

post ure picks in hydro section maybe more help .

DWC systems do not prevent root rot. All hydro systems are highly susceptable to this disease because they all contain water, warmth and air, the perfect conditions for the pythium microorganism which is usually the culprit. You would be better to find a water conditioner at your local hydroponic store and flush out and treat your res. The usual array of conditioners contain hydrogen peroxide and some also have collidal silver as well.

Also try to keep the pH between 5.5 and 6.0. PPM of 400 is fine.

As for the humic acid. I found that the natural pH of humic was a little too high for hydroponics so unless you want to be constantly using pH down, it may pay to use fulvic acid either instead or at the same time when you eventually get to use it, as fulvic acid has a much lower pH. Thats just my personal preference though.

sound advice.

And you could always tone down the nutes for a bit to see what happens. Plants can often rebound when you give them a little breathing room.

It's always a good idea to go a little light on nutes anyway when you're first starting out as that way, you can instantly tell if there is nute burn and can address the problem before it gets out of control.

Sounds like you can probably salvage things here though, so you shouldn't worry too much.

The first few grows are the worst. So much to remember and so much to take control of - but it gets easier after a bit.

Good for you for getting on the boards to learn more about the process from folks who know what to do.
