Hi:

I�m growing indoor DWC cukes, Picolino, under full cycle (seed-harvest) LED drawing 180 watts from the wall- now 12/12 cycle. Very low ppm RO water. Nutes are GH Maxi-Bloom (started with Maxi-Flora) as well as Cal-Mag supplement.

This new seeds I used produced a lot of secondary vines which I was late in pruning. Now there are 4 vines. So far there are 14 cukes on the plant.

I get lots of blooms and cukes, but the leaves develop these dry, tan colored spots on older leaves, but new growth looks good.

Thanks in advance.
