I have two Gelato autos from fastbuds side b y side in a small tent under a Kind LED 300xl light. Both pots are a mix of my own making similar to a coots mix. This is the second round in this soil, amended with ewc, kelp, barley with a few other adds, with a alfalfa hay mulch. One plant is growing happy and green. The other as you see in the pic, isnt. They went to flower a couple weeks ago and got worse since then. I first thought calcium so I added oyster shell powder and some Dr Earths 2-2-2 all purpose. No help. Anybody have an Idea? Thanks B61
you may still have time to re pot to a mix same but with 30-50% perlite or clean river sand to dilute these over nutes soils good luck
Thanks man. Do you really think its over nuted? I was thinking under in one micro or another. Why only one of two plants? Both are the same seed and both are in the same soil. Phenotypes dont look any different. Its kinda driving me nuts. I was thinking about it, and remembered that I used a half assed soil mix for that because it was an experiment of sorts.
Two things to add. The soil I used was half of my regular mix and half of a garden soil I found found in bags at a local Aldi's. It had worm castings and a shitload of bark and things of that nature. I put that toward the bottom figuring it would be good for drainage. Also, That particular plant grew taller and was only 12 inches or less from the LED. I could'nt or did'nt train so is that possibly a light damage?
It looks light bleached. Can you show a pic of the whole plant with the light, exactly how she was growing. Post a pic of the healthy one next to it if you can. Use as many pics as you think you need to show it all. Cheers Os
Am I right in seeing that the damaged or bleached leaves on the sick plant are about the same height and above the top of the healthy plant? If so I would raise the light the difference between the height of the two. cheers os
Thanks Sinse. I did that when I first thought it could be light related. I didn’t go too high with the light so I wouldn’t stunt the other plant. I’m going to tie that tall branch down to the scrog fence if it’s not too rigid. Thanks again! B61
@Bryce61 During the 2 week transitional period between vegetative and reproductive growth, major metabolic shifts are happening within the plant that require increased levels of nutrient availability. Given the information that you've provided, I'd speculate that your soil lacks sufficient levels of bio-available carbon (in the form of sugars/carbohydrates) necessary for effective microbial nutrient cycling during this transitional phase. I'd try watering the plant that's hurting the most with 1T/gallon un-sulfured blackstrap molasses, and see what happens.
Thanks bro. I’m going through all that shit in my brain and have tried a few things. I’ve been watering them with the Bioag humid acid products that have different things for each growing phase.(good stuff btw) I’ve top dressed worm castings. Ground up egg shells and crab shells for top dress. Used EWC from my bin that gets fed mostly fresh seaweed and food scraps. Then lest night all my plants got a bath of tea. Worm castings, kelp meal, neem powder, ground up alfalfa hay and some powdered egg shells covered in molasses. Smelled like neem but got really frothy with life at around 40 hours. Tons of worms in the pots are thriving! Idk. I’m now hoping it’s light or wind burn! B61
IMO those spots are not light or wind burn, I would bet some kind of imbalance/deficiency in available nutrients as waktoo suggested. Seeing you already amended with teas now I would just wait and observe.
