Dear Dr. Weed:

[splenetik]

I have been growing my babies in an aerogarden and recently moved them to a bigger hydro drip system, now 6 days later the leaves are turning yellow with brown spots and edges. The tips are also curling upwards. I have looked at many posts on problems and there are a few the problem fits, can someone please help?

Air Temperature 68 - 77
Water Temp 75.4
Humidity 45 - 59
pH 5.0 - 6.0

If there are any other questions let me know.

THANK YOU!!!!!!!!!!!

a ph of 5 is too low 5.5 - 7 is where it should be so your problem is either ph or over fertilizing what is your feeding regimen?

Thank you, I just raised the pH a little.

Nutes: Fox Farm Grow Big 3-2-6 about 9tsp to the 4gal rez
Fox Farm Big Bloom 0.01-0.3-0.7 3tbs to the 4gal rez

They are on a 18/6 light cycle and a 90 min off/30 min on water cycle.

I greatly appreciate the help! As you see Im a nOOb.

What is this 80 min off/30 min on water cycle?

I would also test the TDS of the nutes.

[splenetik]

They drip cycle is 30 minutes water on and 90 min water off.

I flushed the entire system today, and just put in distilled water, no nutes. I also pruned the bad leaves. The pH is steady at 6.0. The roots look super white and fuzzy.

About how long does it take to see improvements if any? I am still worried.

This is my first hydro crop.

Any other opinions or tweaking that may help?

Thanks,
SpleN

I think you are using less than the strength according to the schedule? It says 3tsp/gal.

ph too low wouldn't help, but I think you might want to increase the nutes
