Happy growing!
My two girls have for a couple of weeks been getting yellowing of the larger leaves. I've tried checking for root rot. None that i could see. I've repottet them to a larger pot(from 35 l to 60l as they both did outgrow the old pot. They have been getting fertilizer about once a week.
Can anyone help me with what im doing wrong?
Overwatering is by far the most common cause for health issues with plants. I'm not too familiar with weed in particular but I can't imagine it being that different from other plants. Nitrogen is a mobile nutrient so when there's lack of it the plant starts taking it from the lower leaves and moving towards the top. Your plant is drooping despite the soil being visibly damp and the leaves are yellowing all the way up and it's looking unhealthy in general too. I think that what ever deficiency it's suffering from is because of root issues caused by overwaterin, not lack of nutriets in the soil. If that is the case, watering with more nutes is just going to make it worse.
Again, I'm not experienced with cannabis so I might be wrong but if I had a generic plant looking like that I'd just leave it be untill the soil dries out completely and the plant starts wilting due to lack of water and then I'd water it. It should then perk up by the next day and look much better.
When I went from regular watering to only watering when the plant is asking for it, my houseplats started thriving. It doesn't work with every single plant because not all of them start wilting when thirsty but it works with most of them.
I started with suspecting overwatering so i have been trying to hold back on the water...they do have leca in the bottom so drainage should be no problem. They are outside however so it is a challenge to completely controll the amunt of water. The yellowing did start on the largest lower leaves and move upwards to what you can see now. I think i will try both a good nitrogen fertilizer and continue to manage the water. Thank you so much for your advice😊
