So I have this clone growing in a DWC under a 400watt MH.

I'm using PBP Bloom, Liquid Karma, Cal Mag+, Fox Farms Big Bloom and Tiger Bloom. Only using pure RO water. (The link to my grow is in my signature)

I pulled this leaf, and 2 others off my plant this afternoon at lights on. There is one more leaf that isn't quite as bad as this one that I left on, but I assume I'll have to pull it tomorrow.

These are probably the oldest leafs on the plant, btw.





Any ideas?

check your pH first i'd say ,,,,hmmm then potasium and or mag def. too??

pH hasn't moved in weeks

I just checked it again, and it's holding steady at 5.6 - 5.8

whaTS yer ppm/ec?

EC is 1.0, falling about .1 every couple of days.

At lights on today, I scoped her out, and things have progressed for the worse. It has spread to more leaves.
That prompted me to go ahead and do a full res. change:

3.5 gallons of RO water
10ml of PBP bloom
10ml of CalMag+
20 ml of Liquid Karma
10ml of Fox Farms Big Bloom
10ml of Fox Farms Tiger Bloom

I also cleaned the roots off. They had quite a bit of sediment trapped up, so I am thinking this might have something to do with it.

Well, the rez change seemed to help. I'm going to lower the amount of Liquid Karma I'm using in the future. It seems to be "clogging up" the roots with sediment.

I'll up the EC with either PBP Bloom or Tiger Bloom.

Good to hear ya got it sorted mate, if all else fails check the roots out i guess, that sediment doesnt sound toog ood..

forgot to ask what your temps are?
