Mi situación empeora! AYUDA

It's not bad mate! It's fine for your others but if you water a to 20% runoff, you'll reduce the potential for issues. I also do something extra once a week which may help you. I water double the amount In one go to clean the soil. So I normally water a 2L nute mix but every other water, I water 2L of plain PH'D water immediately followed by 2L of nutes. I get loads of runoff obviously so I water in the bath 😂.

Thanks @InspireMe! right now I hardly have any runoff! only a little bit of water reaches the drainage tray, I must say that not even 10% of my water reaches the drainage tray. Is this bad? I haven't measured pH or EC (I don't have an EC meter) of the runoff. Although I think it's good theory to attribute it to a blockage! Thanks!

It could possibly be due to your watering schedule. You may have some root issues due to "wet feet." The substrate needs to get a little dry. In future if I were you I'd water until 20% runoff. Only water when the pot feels light.

My real anger is not understanding what has happened since the rest of my plants are in good condition! They have all been treated the same way!

Hello everyone! I'm growing 4 autoflowering plants, 2 Auto Ultimate and 2 Auto Glueberry OG. We're currently in week 8 since germination, equivalent to week 4 of flowering. What you can see in the pictures is happening only to 1 of these plants, the rest have a slight nitrogen deficiency but nothing like what is happening to this one! I'm providing them with 20 hours of light and 4 hours of darkness. The growing environment stays between 20 and 26 degrees Celsius while the lights are on, and at night it drops to about 17 degrees Celsius (maybe a little more on some nights). The humidity in the grow room has maximum peaks of 65% humidity and minimum peaks of 40% humidity. Since germination, I've been using trichoderma and mycorrhizae once a week up to now. I'm using organic fertilizers (complete pack for flowering, nothing should be missing!) and I'm aware that at some point I may have over-fertilized. That's why I didn't fertilize any of my plants during week 7. Coincidentally, in that week and this one (week 8), this symptom has appeared, but only in 1 of them. In this week number 8, I've fertilized all of them again (at the beginning of this week the symptom was showing) and 2 days after fertilizing, the symptom increased on more leaves, starting on the middle leaves of the plant and now it has moved up to some newer leaves. I'm watering with tap water at pH 6.3 - 6.5, drinkable. I try to keep it warm because it's winter and it can come out very cold, so I try to keep it cool to the touch but not lukewarm or too cold. I'm currently using 1.3 liters of water for each of them every 2 days. I think the rest of my conditions are fine: air intake, air extraction, indoor air circulation, lights at the correct height, etc. I'm almost sure, with my limited knowledge, that I have problems with the fertilizers, but I don't know if it's an excess, deficiency, or nutrient lockout.
