Was wondering what the yellow tips on my plants are, plants look healthy but this is what's happening.

Can someone help cure this problem?

It's hard to tell . . . could be slight nute burn or you might need to add a little epsom salts to your feed temporarily. Looks like nute burn to me, but someone will be along soon with perhaps more knowledge of this type of issue.
The epsom salts provide potassium, without which leaves will yellow, but usually all over, not just the tips.

Yes pure blend pro grow it says 1 1/2 tsp per gallon, soil it some kind of off brand soil with no nutesin it, currently went from 4 cfls to 8 cfls 4 75w & 4 100w, about seven inches above the plants it also alot hotter in there but added a nother fan.

Do you people think it could be a lack of potassium?

Its probably ready to repot the way it looks. Back off on the nutes for a while. Repot it with good soil.

That looks like the beginnings of over fertilization. The pot is definitely too small and your plant needs repotting asap.

Epsom salt has magnesium and phosphorus, it does not have any potassium in it.

It does look like your plant has slight nute burn just water for a a bit, if it gets worse then flush it. That's wierd when I used botanicare I got zero nute burn. Botanicare is a complete nutrient and doesn't need to be supplemented. Are you adjusting the the pH the water.

I was useing reg water and went today to buy some distilled water but the water was about 6.5 in ph

I have a electronic soil tester and it keeps saying ideal for nutes, but I will definatly repot quick.

So should I back off the nutes or use less?
