It is either your ph is out of of range or a potassium deficiency.
Dabmastafluxxanswered grow question 4 years ago
looks like an iron deficiency to me ( just from my minimal experience ) but had a similar issue with a single plant years ago, i scraped rust off a pipe and added it to the topdress and it fixed the issue within about a week, the leaves didnt fix but as they started to die off i just ripped the most deficient ones and pruned the rest as more new growth came in lol i wouldnt suggest scraping rust off a pipe though xD i was old school back then haha good luck! :D

A deficiency of either calcium or magnesium usually presents as spotty markings and with associated chlorosis/yellowing.
Personally, I think this is burning caused by an excess of potassium, and not a deficiency of potassium.

Definitely looks like potassium deficiency.

It’s a Potassium deficiency . Pretty similar to Calcium deficiency but starts from the edge of the leaves

Nutrition deficiency or nute solution on leaves during watering?Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag?

I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏6 months ago

PH-Problems in SoilBefore repotting, the pH value in the soil has always fallen to below 5.5. The plants always have an iron deficiency. I then repotted the plants and that worked well for 14 days. Now they are showing PH deficits again. The soil has PH 5,4 -4,8. What could be the reason?Setup. Substrates

Burned tips and white spotsHi, I have a auto plant in its 7th week. Today I noticed that it has burned tips. The white spots have been there for longer, I dont know if they are related to the same problem.
Im new to this and what I came up with is that the white spots could be a cal defincentcy?

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks5 months ago
