yikes. what's your medium/nutrient situation?

looks like magnesium deficiency, but you need to give more info

I keep my PH at 5.5, and PPM @ around 1200-1400

My buds are densing up, but leafs are spotting. We are growing Kinda HYDRO-SOIL (hyrdo resivor with soil).... It worked AWSOME with Shishkaberry, Do you think White Widow is too Sensitive to our method??? Lighting is 600watt hps.

Our water is pretty hard its around 700+ppm but no higher than 800ppm. Do you think epson salt is the soultion if its due to the water being hard? I seen this on a website
Thanks

I doubt it. Manganese is immobile, meaning that only emerging foliage would display the problem. If these symptoms are newly developed, it is probably due to a mobile nutrient deficiency -- probably Magnesium.

I don't have enough hydro experience to comment specifically, but I would drop some Cal-Mag in there and see if that helps. It couldn't hurt.

How much of the cal-mag is sufficient? and also isnt Epson salt an alternative to the Cal-Mag???
Oh yeah, We are using soil... and we use a pre-soak Resivoir with pump and Air stone.

I would use Cal-Mag as prescribed on the bottle. I have a Botanicare feeding schedule here somewhere, but it's on the bottle. Epsom salt is Magnesium Sulfate, so that will give you magnesium ... I've never used it, so I can't comment on dosage, but if you poke around on here somewhere you can probably find it.
