Root rot or over-feeding? Thought it was over-feeding at first but not so sure now.

rividiumstarted grow question 2 years ago

Nutrients stopped for about two weeks now. There's a slight "planty" smell in the tent, not quite musty, but all the leaves near the top have crisped up and died, soil is compact and doesn't seem to absorb water. However, new growth at bottom is lush and green, thrown by that.

Boy, you've got me stumped... you really do! All I can tell you is that the plant is basically toast which you know already... The only thing I'd like to point out is your watering... I know, reading through every week of your diary, you were concerned that you might overwater ... but I think you were TOO worried about that. Overwatering is a state of always being wet... never having the soil dry... and overwatering is more of a concern when the plants are really young - from seedling to veg... I noticed also that you were on a strict schedule as to when you watered and what day you gave nutes... A better option would be to let the plant tell you when it needs something... from veg on through harvest, get used to juding when the pot is dry by picking it up ... if it's super lightweight, it needs something... you can actually get to tell when there's just a little bit of water in there and even WHERE that water might be... but that's beside the point. If the pot is heavy, don't water... if the pot is light, water... And also most people will follow a schedule of water/feed/water/feed or water/water/feed/water/water... so you MAY be feeding on Sundays - but you might also be feeding on Wednesday or any other day of the week. The other thing about watering is that when you DO give it just plain water, you need to water it enough so that there is water running out from the bottom. I always have a saucer under my pot and when water runs out, I let it sit in the saucer for about 15-30 minutes to see if the soil soaks it up from the saucer - and it usually does, especially if I've let the plant go a day too long - the soil gets so dry, it can't soak the water up immediately and it runs out. I water mine until there is standing water left in the saucer... if the plant soaks it up, I give it more water, etc. After 30 minutes or so, if there's still water in the saucer, I dump it out because you don't want your plant to have "wet feet" which could lead to root rot. What having this kind of runoff does is helps the soil clean out the excess nutrients and the salts that might be building up in it which could cause things like a calcium lockout... meaning your plant just can't absorb the calcium even if you're giving it calmag.. I have ZERO explanation for why your plant died so quickly or why your soil seemed not to absorb water... everything I've read about that condition just seems not to apply... I'm sorry your grow ended up this way - but don't give up! Good luck

I think is the cause form over feeding. The plant was using more water in the top growth because that is where the most light is. and when it is sucking up the water it does not control how many nutrients are in it, they buildup in the leaves and burn and crisp up. The lower growth is doing fine because the light is not as intense and this they are not sucking up as much water that is over feed. It is a double whammy when some of the water is evaporating out then it increases the concentration of the nutrition in the medium suspended in the water. Fox Farm susgests in its feeding guidelines to flush the plants a lot as well once every 2 or 3 weeks I think, will need to check their feeding schedule. To me that is dumb, if you are feeding the correct ammounts a flush will not be needed... fluses are only need to correct a salt buildup from incorrect feeding. If the company is advertising you to flush they are willingly and knowingly exploiting you to but more products at the costs of potentially hurting the plants. I would invest in a TDS pen that measure EC/PPM and use that when feeding liquid nutrients to find the sweet spot. sometimes they could be 1/4 to 1/2 the recommended strength of the manufacture. The size of you plant will also make a difference as bigger plants eat more and some strains don't like as much available nutrients. like autos. they are in a category of their own. I think you should perform a flush and they feed 1/2 the recommended till harvest. the yield will suffer because of this misshap but now you know for future grows.

High rividium, The only reason for leaves to dry out like this is due not enough water inside the plant to cool herself down. When trees and plants “sweat,” they cool themselves and can cool the surrounding air. Through a process called transpiration,water and nutrients are taken up by plant roots from soil and delivered to the stem and leaves as part of photosynthesis. There are multiple reasons why a plant can not transpirate enough. Instead of writing them all here I send you a link from the Royal Queen Seeds company website. They wrote a great article where they explain all the different reasons with pictures to make it clear for yourself what could be your reason. And also how you can solve this problem and to prevent for future grows. Here is the link: https://www.royalqueenseeds.com/blog-how-to-prevent-and-treat-dry-and-crispy-cannabis-leaves-n731#:~:text=Dry%2C%20crispy%20leaves%20are%20one,few%20of%20the%20common%20culprits. Goodluck and I hope that you can find out the reason and still get a great harvest from these plants!
