Leaf spots issue
Budcultivatorstarted grow question 5 years ago
Does anyone know what is causing the leaves to look like this?
Throughout the whole grow i've had brown spots as you can see in the older pictures, although adding calmag didn't really fix the issue.
If anyone has an idea of what this could be please let me know!

I'd try water-only irrigation - just as you apply fertilizer, hopefully... no flooding or anything..
As far as adjusting the ratio of what you feed -- it's one plant, so difficult to say, but if this is common, yes. at the least, make a note for this strain for future reference if you plant to clone it.
i'd give an irrigation or 3 first -- an EC meter can help determine how long this is needed. Get the concentration back in check, then think about altering feed -- or how often you feed.. so many ways to accomplish similar goal and which is best for your context just depends.
i'd go a week and see what happens with water-only... if it takes a nosedive or shows obvious deficiencies, reverse course.

Would flushing then be a good solution? Or would lowering or altering the nutrient ratio be sufficient?
Thanks in advance

I would guess some kind of nutrient lockout at some point or buildup of salts... Could be spillage from waterings perhaps? 🌱👍

possibly, Ca def, but if you've provided that, don't add more. (check labels.)
i have a nutrient spreadsheet in week 7 of ggxww that might help you... the liquid portion needs some verification, though. thorough instructions inside spreadsheet as to how to use.
a P/K tox could lockout Ca and cause that symptom... double check pH is 6.5-6.8 of anything you add to your soil. i think this is more of a ratio adjustment needed of what you feed.

PuzzledWhy did my seedlings germinate with white tipped leaves? I have seen this happen before a couple times and I am curious as to what the issue may be. Is it genetics or germination technique (pH, soil to hot, too wet)? In the past, the tips will brown and the plant would been fine.

Question about the leavesThe leaves of my lady are folding and hanging. I locked out Underwatering by giving them new water and nutrients last day and overwatreing cause the leaves would then folded upwards. But the have folded downwards... What is the problem? Have I overseen something?

What am I facing? Plant is getting worst everyday, and I can't find the reason why. Thought it was a calmag def, but now I don't really now.When I switched to flower, I started watching some rusty spots on the leaves of the gelato.
After doing some research, I thought I was facing a calmag deficiency, and starting adding some calmag.
Plant is getting worst, I flushed the roots and water between 5.8 and 6 as canna ask
