Something is a little out of balance in your mix, because it is healthy otherwise.
K-def, S-tox, P-tox... if you can calculate the PPMs of what you've fed your plant over time, you could deduce what it is fairly easily. check out my nutrient spreadsheet or google for a nutrient calculator to convert your labels to PPM and add it all up.
k - <210ish ppm and even that can cause some plants issues.
p - <60ppm
S - <110ish
Generalizations... ballpark firgures of upper range
A lot of this depends on the ratios of nutrients as well as the pH. A significant shift in either can drastically change what "optimal" is.

My first guess would be Nutrient Burn, if you're using nutrients, just cut back a little and see how your plant reacts.
My other guess would be the early sages of Potassium deficiency, although this is rather rare if you're using quality soil.

Yellowing edges and brown tips in 7 week of flower.Hello, fellow growers. Need some help. I'm in 7th week of flowering and upper leaves start yellow with burnt edges. The lamp was too close(30 cm) for 3 days. I raised it to 50 cm ten days ago, but the symptoms are stil progressing. Is it light burn or potassium deficiency?

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?

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

What is that?Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6
Increased light intensity to PPFD 600.
This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick.
If it's a light burn, why not on upper leaves?

Grower questionAny ideas what the issue could be?
Few weeks into flower. Dealing with fungus gnats and have kept the population very low.
Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED).
I have adequate air flow.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect.
I should add Dolomite Limestone to the soil this week.
