Looking like your nutes aren't balanced and/or strong enough. Those leaves are being scavenged for nutes from the growing tops. The first 3 weeks of flowering during the stretch the plants eat more than any time during their lives and there wasn't enough food so they steal what they can from the older leaves.

I don't know what nutrients that worm stuff has but if that's all you're using it's not enough or it doesn't have everything plants need. I'm seeing low P, N and Mg at least. Don't want high N in later flowering but need some as well as lots of K with some P. Epsom salts will fix the Mg and add some sulfur to produce more resin but some decent nutes are definitely needed.

:peace:

Wow. You are new at this eh. :)

NPK are the basic nutrients and are usually on the label of fertilizers.

N is Nitrogen
P is Phosphorous
K is Potassium

Those are what are known as Macro-nutrients and are basic to all plants.

Magnesium, Mg, and Zinc, Zn, make up all the mobile nutrients with the NPK and can be stolen from older leaves by the growing tops of the plants when the roots can't find them

Calcium, Ca, Sulfur, S, and all the other micro-nutrients are immobile meaning once the plant has used them to build leaves etc they are fixed in place and if the plant can't find them in the soil with it's roots then growing parts of the plants will start screwing up while older leaves will remain healthy unless the mobile nutrients are lacking then they will go bad like the ones you have.

Do you have access to a garden center or hydro shop where you can buy better nutes? Even some tomato food would have most everything pot plants need but stay away from Shultz and Miracle Grow stuff as it's meant for flowers and has a lot of contaminants that aren't meant for consumable crops like food or pot. Don't go overboard with any nutes you get as more is not always better.

Any brand name on those worm nutes you are using so I can look them up?

Get some of these books. The Basic grow one from Jorge Cervantes would be a good one to learn more about the basics of growing pot tho it has a lot of stuff in it too.

I found a great spot to download FREE POT BOOKS. I downloaded a grow bible first and got lots more. Books look great and complete like the real ones I have here. No web site but just a page of links. Just right click on what you want and then "Save Link As" to download so they don't open first as some are 50+ megs. They got lots. Enjoy.

I would double your next feed and see how that goes. Decent balance of P and K for flowering. Get some Epsom Salts from a drug store too and give them a tablespoon/gal/4L. Those are dirt cheap and should come in small containers. I buy 4KG jugs of it for hot soaks in the tubs using 2cups with a cup of baking soda to help my arthritis. So relaxing. :)

For plants epsom salts supply magnesium and sulfur.

In the bath they help detoxify the body and supply magnesium which is lacking in everyone who eats a typical western type diet rich in processed food type substances and lacking in fresh produce. Even fresh produce is lacking in many minerals that were in them 50 years ago due to the chemical destruction of soil bacteria and the reliance of artificial fertilizers to grow crops.

You should carefully study this chart and pay attention to the various clues around the pics. One symptom does not tell the whole story so it takes some sleuthing to figure out what is really going on. You can download free pot growing books from the following link as well.

What to do if there are a lot of deficiencies ?

If everything is screwed up then most people flush out the pot with 3x the volume of water to remove almost everything and with the last load of flush water add about 1/4 to 1/2 dose of well balanced nutes and pH it properly so the plant starts fresh with something to eat.

Sometimes that's the best you can do.

Not a problem if you can add some nutrients as you do the last part of a flush.

With any luck you'll have a better yield at the end.

What are you growing in and what strain is it? Your npk is a 2.7/1/2.5 is that right cuz you have it down as nkp .

If its blue dream I was told that it likes nitrogen maybe you didnt feed it enough nitrogen in veg and it looks n and p deficient to me.

I wouldnt flush now if you do hit it back with full strength nutes since your in flower, if you were in veg then I would say hit them with lighter nutes. Up your P a bit.
