no it doesnt kill the plant just change what ever feed you are giving it. If you are not useing any feed start giving it bloom feed some arenot right for certain plants i had that too all thru out the stages of veg and flowering, I have it right now it seems that they grow out of it it should be fine but that very last pic looks like the leaves are not getting their nutes. TRY this flush with water from the store for the next five days maybe two times or three times in the next five days. After that start adding very little bloom nutes and start over again.

no i cut off the affected area and the rest of the plant is still ok, i bought some nutes to fix the problem (phosphorus deficiency) and i stopped watering so much to help with the iron deficiency.. a couple other of my plants seemed to have the same problem starting, i tried neem oil and hydrogen peroxide but neither helped which means it wasnt fungal or bacterial.

ill update you on my progress with this once my nutes arrive

although the other plants that had this starting have since cleared up a little bit with me watering them less

Has anyone ever heard of purple widdow. I went to go check on it after i read all the suggestions and the coloration has started to turn purple. This is a clone of a widdow plant.

Hmmmmm

bummer that sux balls

Does purple mean that it could be bud rot?

I know it's been a year, and this is not really a concern anymore, but just for the record, judging by the appearance of your bottom leaves, it is for sure a potassium deficiecy causing the purple color, potassium is known as a color changer, and can be used as a cosmetic effect to your buds, but you don't want to go deficient until just before harvest. when the outer rim of your lower leaves is yellow, with the middle still green, which I see in some of your pics, it is definitely a potassium problem. I use a a mix somewhere around 10-20-15 for flowering, keep your potassium above you nitrogen in this cycle, but lower than your phospherous, when in vegetative cycle I to prevent K deficiency I use something like 15-10-10, keep the P and K just below the N.
