Anyone want to guess the Problem. Jilly Bean. Is this a Mg Deficiency???

Strain: Jilly Bean sativa



Setup: Plants are currently in 6" net pots, hydroton, 18 gallon tote, with an aeroponic setup inside. I'm waiting to finish up my UCDWC setup so I can transfer them into that.

Water Temp: Water temp has been around 75 degrees on the high side and when I add water bottles, 55 on the low side until it warms up a little.

pH: I am using RO water and Botanicare Garden Grow at about 400ppm right now. My pH meter broke, so I am doing weekly water changes in an attempt at keeping the pH at an okay level until my new pH meter arrives.

Air Temp: between 80-85 degrees

The other few plants in the same tote seem to be doing okay and not showing these same symptoms as much as two.

hmmm..the plants that have the brown,,is there a "bubbler" close to them in the resevoir?

either cal def of mag def get you some calmag or epson salt either one will solve the issue

Thank you. That was also my feeling. I purchased a nice RO Filter and didn't realize that it would rob me of the Ca and Mg. That explains why when I switched from the distilled to the RO the problems started showing up.

Thanks everyone. Love this site!!!
