Yellowing leaves
    #259519 - 08/04/09 02:59 PM (8 years, 8 months ago)

My leaves are yellowing more in the middle of the plants.  I have eight plants a little over three weeks old.  Everything has been going just fine until I woke up this morning to greet my eight friends and they had yellowing.  I started a new nutrient mixture in my reservoir yesterday with a ppm of 900 from my last mixture which was 500ppm also with a pH of 5.6. my pH is a steady 5.6. I feed with a drip system of two mins. every three hours in Rockwool.  This feeding has worked fine so far until I noticed the yellowing this morning.  Is this a Nitrogen or some other deficiency?  Or over neutralizing? Because I really don't think it's over watering.  Please help...

Do you have mold on top of your rockwool? Also does your PH drift at all?

a couple of things. It looks like a N deficieancy. As the plants grow, you want to increase your ppm. You should keep it at your 900 increase for at least a couple of days and if things are improving, your heading in the right direction. Also, 5.6 is obviously in the acceptable range, but try upping it to 5.8 for a week and see how they like it. that is the magic number for my girls.
