Leaf fade vs. deficiency

Homegrown93
Homegrown93started grow question 4 years ago
Hey everyone, does this look like a deficiency? I’m in week 6 of flower, I had half a week of high temperatures and I’m sure she was affected just a bit and noticed Bud growth slowed slightly. Not sure that influenced this and if it’s a deficiency(magnesium?) or normal leaf fade.

Normal. They are some of the oldest leaves at the bottom of the plant. They are also in the shade now so just let them yellow until you can easily snap them off or they fall fall off on their own. By Week 6 of flowering- moving forward, you should see a slow but steady yellowing off of most of your plant’s oldest lower canopy leaves. If you notice that this is happening quickly all over the plant, then you have an issue. If you feel she needs a little boost, you could give her some extra nutes. A little goes a long way so I like to use a compost tea at this point. Even a weak solution will quickly and gently feed your plant top to bottom without burning your already weakening leaves or leaving a harsh, nasty taste in your buds. All the best with your upcoming harvest! 😷

Thanks for the input!! I initially thought nitrogen might’ve been the reason, but I actually started seeing obvios signs of nitrogen toxicity just before this. I figured it had to do with the coco nutes being a bit stronger in Nitrogen so I slightly decreased the part A of my nutes. Not sure what to think

It's nitrogen defeciency, at this stage the plant needs little nitrogen and will take it from the lowest leaves. Nothing to worry about in flower, is quite normal unless they all yellow🌱👍

Hi! This look like a Nitrogen deficiency (older/lower leaves going yellow), but it's may be the result of other parameters. Senescence is improbable after only 6 weeks of flowering, or maybe this strain is fast (check the trichomes). For your high temperatures issue, you must try Elycitor from Bio Technology. It's basically a mix of bacteria, but my room goes up to 34°C last summer and that didn't bother any of the 4 plants in it. ^^
