[jjd031]

In 6th week of flowering, DWC bubbler, 6 plants in 18g tote, DynaGro and now DynaBloom ferts all the way 1/2 tsp. per gal. Change watter every wk. 3 6in. air stones. 1000w hps and a 600w super sodium. 2 fans running 24/7, the fan on my 1000w broke need a new one. All 6 are clones from my last grow in dirt.
The leaves are getting brown spots starting at the outsides of the leaves moving inward or down the pic is a leaf cut from the kola. Is this how a natural n dif. looks at the end??
The last 2 are the different strains or types the the other 5 plants 1 is dif. then the rest.

Couple things......please take photos with you HID lighting OFF so we can see the true colors of things.

That said, my first guess would be nute/salt/fert buildup in your medium, requiring a good flush of your system.

Good luck.
