I am posting pictures of the nutes I us and want opinions on what I should cut out or cut back on. I feed in soil, so I mix into water.. (Advanced nutes) Sensei Bloom part A and B I usually feed (3 1/4 teaspoons, to a gallon of water)
i proceed to feed Big Bud (1 1/4 teaspoon and 2 1/8 teaspoons to a gallon of water) and B-52 (1 1/4 teaspoons and 2 1/8 teaspoons to a gallon of water)
I am attaching pics so yall can let me know what to cut back on and what not.

@mr sunshine but all my bloom nutes have a ton of it at least 3% for the part A and B, and 2% for the B52, should I just cut those out and only feed it big bud? or should I just heavily cut back on those three nutes (Part A, B, and B52)?

Maybe once a week, my more healthy girl is starting to droop so she needs feed. I was gonna feed her after lights on... So just cut back on anything with N and leave the rest as is?

It's amazing how easy it is to over nitro pot plants, especially autoflowering plants. My plant did ok, but had really dark green leaves which is one symptom of over doing the nitrogen. I call on makers of nutes to redo their feeding amount charts.

I agree it is easy to overfertilize. But I don’t agree about nitrogen. Most burns and premature yellowing during flower are from too much PK.

Bloom products are not needed. I use a Grow ratio all the way through.

In this case pure Blend Pro Grow. But any complete balanced Grow nute will work.

This sativa leaning hybrid is an extreme example. She flowered 12.5 weeks. Gets harder to keep them healthy that long. When she started to burn at the edges I just leached the pot with a gallon of water and the fed with less grow nutes. She recovered right away.

Well I think the opposite plants you said are doing better but my advice I used on the plant above is what I do anythime I see leaf stress.

Run some fresh water through the pot. About to 20% runoff. Take readings to see ppm and ph which is very telling but not necessarily accurate at the root zone.

Then run like 25% to 50% of a base complete Grow ratio nute through to runoff also and see what comes out.

Then wait. It will take 3-5 days to be sure of improvement starting.

Do not water until pot is very dry and light.
