Leaves with a potassium deficiency get yellow, brown, or burnt edges and tips. The burnt edges may look a little like nutrient burn, except the affected leaves also start turning yellow in the margins. Yes to much can actually lockout nutrient intake. Flush with pH water and resume but go easy on feeding

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

Sick leaves, good budsSome leaves look sick. (Last photos at 8 weeks) Is this an overdose? Do I need to fix this? From fertilizers, I apply only ripen. I plan to give it 2-3 times and then flush and harvest.
I know that ripen helps to end life and makes the leaves turn yellow, but not so!6y ago

Nitrogen toxicity and tip burnSmallest plant (1st pic) was showing nitrogen toxicity and I just fed distilled water at 6.3ph to try and help. Bigger plants had some tip burn and curling up. Thought this would help them. Any tips on how you would treat this please?

Problem with front middle purple punch. Info provided(See description for more); Temp: 71-79.5F, RH: 46.1, DLI: 40-50(decreased today due to tacoing)This is an organic grow using Coast of Maine Organic plant food, and lobster meal. It appears to me that the plant has deficiencies for all the three major nutrients, or lockout, but today it is also showing what appears to be Calcium or Magnesium. I've been using castings too.

Suddenly, massive problems. Tried a lot already, nothing helped yet. Any ideas what I'm missing?Hey guys, I've been growing for a few years now and something like this has never happened to me. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures).
The box worked fine for several grows

Dry yellow tipsI've noticed a few leaves have developed some dry tips on the ends including some of the new ones coming through. Can anyone tell me what could be the problem? Feeding bio grow 2ml per l at the minute. Is it a deficiency of some sort? Or nutrient burn? Worth sticking to water?

Dying leavesI had some mild nute burn last week on a few plants. A few tips were burnt. Some lower leaves are turning yellow and dying. Is this still nute burn or something else?
