Week 5 of flower should there be a few yellow leaves like this? I use tomato feed as a nutrition and cal mag and sea kelp every other water
Just had this problem last week and seeing the fuckers fly around I supposed it was the gnats in the dirt. I rinced the roots and repotted the plant in some dry and healthy dirt. Been 4-5 days and only saw one gnat (poor bastard must be lost in the basementWeek 5 of flower should there be a few yellow leaves like this?

I would like a look at end product. Been almost another month since last post.I'm not sure of what your tomato feed has in it. (You keep hearing that huh ... lol) What brand nutrients is it? I'm not convinced your tomato feed is your problem. Likewise, I'm not convinced that it isn't. There's way too much stuff going on at this point in your grow to be able to accurately diagnose what is happening with your grow without detailed information. (Temp/lighting/watering program ... about every detail of your grow is beneficial in some way).
This much I can tell you. At week 5, there should still be plenty of green through out your plants unless its a very fast finisher. To me, it looks like it could have gone another week or so before cutting back on nitrogen. If you have not added it prior to flower, don't add it now. Your grow doesn't look bad. Some leaf yellowing, especially in the lower part of your plants, is normal. However, the idea here is to try to keep it green as long as possible. Senescence will eventually cause color changes no matter what you do.
If it were my plant, I'd be looking for a potassium sulfate boost. They are frequently sold as "bud sweeteners" in the cannabis nutrient industry. Since you're using tomato feed, I'd guess you're not in a legal state/country. Potassium is needed in fairly large amounts (don't get crazy, stay by the directions) during flowering. So is calcium but you're already using calmag. Find yourself a way to boost K (potassium) and I think you'll be happy with your grow come harvest time.
P.S. I don't see signs of a huge K deficiency. I'm simply suggesting adding K for flowering support. You will likely run into a K deficiency before your done with your grow without a way to supplement it.

We need closure on this anecdote.

As stated above, they won't heal. Remove them from the plant.Yes, trim those yellow/brown leaves. They won't recover.
Thanks dude!Yes, trim those yellow/brown leaves. They won't recover.
Excellent info! Thanks alot manThere are times you don't want to be plucking your sicklies and yellows. Clones are one example. Until they develop roots to take in nutrients, they will draw mobile nutrients from a single fan to provide the rest of the plant with nutrients in a selective form of cannibalism. You pluck the yellowing leaf and you're cutting off the plant's nutrients and it has to select a new leaf to cannabilize off of.
Another instance is when a plant is way overfertilized. Those leaves that turn sick are the sacrificial lambs to absorb the toxic levels of nutes. If you pluck them before they fully burn, the plant will just select more leaves to try and purge the nutes. Sure they need to be removed, but not before they serve their purpose.
But leaves turning yellow from insect predation or getting attacked by fungi should be plucked immediately and thrown in the incinerator, lol.
Sick leaves can spread disease but some leaves get sick as a means of the plant trying to heal itself.
I just got done trimming them. Thanks man!As stated above, they won't heal. Remove them from the plant.
