Leaves with brown spots on them

Gator01 · #1 (**permalink**) 11-08-2006, 02:15 PM

Does any one have any idea what is causing the spots shown in the pic below? Im running bubble buckets and a 8 bulb t-5 fixture and doing LST. The pH is about 6.3 and the PPM are in the 1800 to 2000 range. temps have been ranging from 68 to 70 at night and 80 to 85 during the day RH is running in the 55% range. The plants ate THAIxSKUNK and are on day 14 of flowering. any ideas?

PS the spots are on the older growth only and has not shown on any of the new growth in the past week or so.

Yup, pH is a tad too high so I'd try fixing that first:

i'm no expert but that's how mine looked with a spider mite infestation. Check the underside of the leaves witha magnifying glass to be sure. Good luck dude
