There has been problems with my plants, at first I thought it was nutrient toxicity but the problem continues (on new and old leaves) even after being flushed two times.
My medium is a 70/30 coco perlite mix, pH from 5.5 to 6 and EC between 900 to 1k.
Here are some pictures:
I’m very much a novice myself but to me it looks more like some little critter’s been having a taste of her leaves than it does nutrient burn.
I could be wrong but I’m sure someone will be along soon to offer a more experienced analysis. If it is, you’ll probably just need to give her a spray with a neem oil and horticultural soap mix. Treated mine with it a little while back and it worked really well.
Anyway, good luck!
Nothing super alarming in those pic mate. Looks like some ph fluctuations and maybe a little root stress. In veg try to aim as close to ph 5.8 as you can and avoid fluctuations of more than 0.1 day to day and she will like it more. The twisted leaves are probably due to root stress but check the plants carefully for any bugs. There are insects that can do that but it’s not common. All this is most likely due to variations in the feed. Sometimes it’s trial and error to find exactly what each strain wants but your grow isn’t in any immediate danger. Have you checked the EC of the runoff?
In coco keep the feed at a constant level and measure the output EC of the runoff. If the runoff has an EC 200 higher than the input, drop the input EC down 200 for the next feed. Inversely, if the output EC is more than 200 lower than the input raise the EC. This will allow you to find the exact level of feed your plant wants. Avoid making large changes and try to find that happy spot. Plants thrive on consistency but don’t go crazy trying to get exact feed EC numbers, they can handle a little fluctuation here and there. If you have flushed twice the salt build up should be gone. Once you get some runoff data the feed can be adjusted as needed. If she was in my tent I would not be concerned at this point.
Great advice Monkey!!
Dang @MonkeyDo A1, you truly know your stuff 👍👍 I'll have some questions soon FYI
I wouldn't worry much! A bit of yellowing is normal during the cannabis plant's lifespan. Feed her and watch you watering habits as well as temperature and ph, and keep checking the plant for new symptoms or wellness
