Per guidance in another thread, my four outdoor plants have 4-6 weeks to go. One of them has a lot of yellow leaves all over and at the top. I have some liquid seaweed organic fertilizer mix that’s classified as 0-0-1. I believe I need nitrogen and wonder about using this stuff. Although it has the zero for N, supposedly the other components combine to create growth for outdoor plants. Thoughts?
Late stage nitrogen?

Can I see photos of your 4 girls outside with 4-6 weeks to go because I have 4 plants outside with 4-6 weeks to go and want to see if I am on the right track with my growth?? Although they are all the same strain, each one grew differently as well. Thanks!
Best one I have for now, about a week ago

If it’s yellowing are the top and bottom but not progression linearly then it could be N deficient and also too much P/K causing yellowing in the newest growth.
Also magnesium deficiencies usually show up around now and cause interveinal chlorosis in the middle of the plant.

All, here’s a pic. It’s tough to demonstrate but this one has pale green leaves throughout vs the other three. I’d picked almost all of the yellow ones off a few days ago, not realizing this forum existed. Thanks.
PS: what exactly does the liquid seaweed 0-0-1 do anyway? I’d read about using it in many articles but if it has no nitrogen and the other two are 0-1, what’s the benefit?

I did two feedings with 10-10-10. One upon transplanting and another a month later, none since then. Quantity was what the instructions indicated to use for the relevant square feet of the grow, I don’t recall the figure.

Phosphorus deficiencies cause dark splotches on leaves and can appear at the bottom of the plant on some of the oldest leaves. Learn to spot & fix the issue.

not perfectly round ones like those. i'd scope the underside of the leaves.

It looks kinda generally hungry. Like it's running low on everything. If 10-10-10 is what you have, I would use more of that. If you didn't burn your plants up last time you used that fertilizer on them I would follow the same set of guidelines again. Too much of any 1 nutrient at a time can cause problems. If you use a Reasonable amount of your all in one you should be OK.
Liquid seaweed has a little Potassium and a little bit of a bunch of micronutrients for "fertilizer value." It also has plant chemicals that stimulate root growth, or lateral branch or tight nodes spacing. So it can also be used to foliar sprays to help out cloning or shaping your plants.

Dude you’re lucky. It’s only slightly N deficient - simply feed a balanced food like 1-1-2 or something and it should stop the liming of the leaves.
