Nutrient problems

Hello,
Im using hydroponic system - with microcapillars,my plants are 2weeks old and they are showing some nutrient deficiencies,but I really don't know what am I doing wrong.. I use Flora nutrients (grow,micro and bloom + CalMag,my pH is about 5.8-6.1, Ec is 1.4 I use ROwater and also I tried tapwater.Humidity is about 40-70%,air circulation is perfect I also have CO2 bottles and feeding them every 2hours for 15minutes,600W HPS lamp and temperature is about 23-26C.

And yes pH and ECmeters are well calibrated (both from Milwaukee)


I have royal queen seeds (royal Jack auto)
I"ll be glad for any help!
Thanks.

What ppm are you running?

Think you may be overfeeding. At 2 weeks I usually run very low to no nutes on my autos due to most of them being much more susceptible to burn. I have a couple now that I can't run over 450ppm even as adults without issues. That's just my experience, we'll see what the others think. Happy growing

That sounds like a lot of nutes for such a young plant, mine are quite finicky feeders though and I usually find easing off on the nutes for a few days tends to put most things right

yep,, try EC around 0.5 to 0.7 for plants that size.

I´ll definitely try what you adviced to me and let you know how am I doing

Thanks!!

And my PPM is about 980..
