These plants are about 4wks old sprouted from feminized White Widow photo seeds (Crop King). They started out great then two plants started getting brown, dry leaves at the end of the leaf which eventually affects the whole leaf. This began at the bottom of the plant and moved upward. The other is thriving nicely. The leaves are just turning brown and falling off. Not all plants are doing it - just 2 out of the 3 that sprouted. The plants in the photo are from the same seed and have had the same amount of soil and watering (every other day).
I'm running a 480w 'quantum board' w/ LM301H diodes about 20" from the plants on an 18/6hr light schedule. Using Fox Farm Happy Frog soil (Ingredients: Composted forest humus, sphagnum peat moss, perlite, earthworm castings, bat guano, humic acid (derived from Leonardite), oyster shell and dolomite lime (for pH adjustment to 6.3-6.8 ) in 5gal cloth buckets with no added nutes - just water. I was thinking it looked like a Phosphorus deficiency so gave it a little fertilizer with high 'P' but no change. My water (tap water) pH is 7.00 and the plant drippings measured 5.8 (is that normal?). Any suggestions are appreciated...I'm totally stumped and these plants are going downhill pretty quick.
