Yellow/brown spots on my leaves

We’re you able to fix the yellowing spots? I am going through the same thing with my Pineapple Express auto. Thought it was a cal/mag problem, but it got worse after adding.

Это нехватка калия

It does look like calcium deficiency. It might check your ph, because maybe there's calcium in your medium/water, but it might be locked out of the roots because of incorrect pH or too much potassium. Take a look at this: https://www.growweedeasy.com/cannabis-plant-problems/calcium-deficiency Also, it can take about a week to notice changes in new growth, and that is where you should look at, even when the deficiency is fixed, the leaves stay with the brown spots.

You need to know what you feed to make an educated guess here -- even then it is still a guess, butnot a blind stab in the dark. toxicities and out of balance ratios of nutrients can cause any and all symtpoms.. and adding the wrong thing only makes it worse. if not armed with this knowledge, you can't do anything useful that isn't pure luck. calculate from your labels ppms (molarity is better, but no one uses it for comparison reasons, stick to unsophisticated ppm) of what you feed.. google a bit (e.g. rollitup has some nutrient fomrulas of various brands in a nice post). Get an idea of what is normal.) if you provide plenty of Ca, it's clearly something else... if not, you know to stick with it. It won't heal in a matter of days. Ca and Mg take upto 4-6 weeks just to show symptoms from onset of problem. Those rust spots don't heal, if i recall.

Hi there! To me it sure looks like cal def but have the symptoms gotten any worse after adding cal/mag? The leaves wont recover but symptoms should not spread. Do you know the pH of the soil? Also too much magnesium can lock out calcium so adding cal/mag wont necessarily help if the balance is not right in the soil cos you keep adding more magnesium too. Also too much P and K both used an excess amount will lock out calcium too.

The deficiency and the lack is close, you already add calcium (I had not seen on your question) but are you sure that this is not precisely an excess?

Calcium deficiency or insufficiency? your opinion ?
