Help with brown spots please?

shuffler76 · #1 (**permalink**) 08-16-2009, 12:01 AM

I am a 63 year old newcomer to growing and this is my second effort. I have made a forum search and read what Cervantes and Green both have to say about this plant condition but would like further advice.

After 3 weeks I noticed some brown spots forming on one of six Strawberry Cough plants growing in my homemade bubbler. I am thinking this is a magnesium / calcium deficiency but not sure.

The little ones were getting 200ppm General Hydro Flora mix which I have now upped to 400ppm. They are presently six inches away from a 65 watt fluorescent fixture.

Any help or advice will be well appreciated.

Thanks for the reply. PH is 6, water temp is 75 F, Air is 72 to 76 and humidity around 30 percent.

lower the PH to 5.5-5.8 optimum range

Thanks for the help gents I'll fix that right away. It will be easier when my meter arrives, presently I am using the GH Ph control kit.
