Need To Correct Yellowing Leaves Throughout Flowering (Week 3 - Week 6)

All 3 of my outdoor plants (all different strains) have had the same consistent symptoms during flowering. During the first 3 weeks of flower, I slowly decreased my dose of Maxsea 16-16-16 from full to about half while working the dose of Flower Fuel 1-34-32 up to full. The exception is the Strawberry Banana, which I fed more heavily during these three weeks because I could see a pre-flower N deficiency.
It recovered well from the deficiency and from week 4 onward I have been giving all of the plants: 1 dose (1-34-32), 1 heaping quarter dose of 16-16-16 (~5-5-5) as well as molasses and occasionally Epsom salts. My Orange Bio-Diesel and especially my LA Wedding Pop have had yellowing leaves near the bottom of the plant throughout the last 3 weeks of flower, but it hasn't been too bad and I've been trying to correct it by either adding Epsom salts or increasing 5-5-5 dose slightly. I wasn't concerned until my Strawberry Banana, which had been looking good got decently yellow again. I was hoping to get some advice on how to correct it or if I should even worry about it during flower; the plants seem to be healthy otherwise. Thanks in advance. Take a look at the pictures below.

Yellowing bottom leaves is generally normal throughout the Bloom phase. I think the plants look great! If they were my girls I wouldn't be too concerned. Looks pretty normal.

I would hit them with more epsom salts....maxsea does not have enough Mg....best of luck

Sweet thanks for the replies. I will up the epsom salts and go from there.

Jack's classic..start til finish. Water one week, feed the next ..repeat til harvest. Idiot proof.

I'm proud of you bro! But for the rest of us who get yellowing bottom foliage in flower, there's no need to freak out. Plants often take nutrients from those useless bottom leaves and send it where it's needed (the buds)

I've also seen growers with green plants all the way through harvest, and then the buds are dried there's nothing there except a spindly foxtail. You can feed your plant veg nutes all throughout their life and you'll keep them green, but you won't get fat buds come harvest time. Might not get buds at all!

Sounds like horseshit to me.

What does? Give a plant grow nutes it's whole life and it'll stay green af! You just won't get any buds. All I'm saying is judging your success by how green your plants stay throughout flower is goofy. And giving your weed 20-20-20 throughout it's whole lifespan seems a little goofy as well. Why would you give a flowering plant such proportionately high levels of N? I think any experienced grower would tell ya to taper off of the Nitrogen after the first couple weeks of flower.

I feel we have to keep up the N dose well though the transition to flower ~ week 3. My plants love life.

I worried about yellowing leaves the first time I grew

You're a clown, try it before you criticize it. There are dozens of threads of growers using jacks classic 20-20-20 start to finish.

There's dozens of threads of people who think the Earth is flat as well. HINT: It's not

And you realize that Jack's is owned by Miracle Gro right? Lol. I suppose you could just use classic Miracle Gro and it'd keep your plants green too!

I don't give a fuck who owns what..I use what works best. I can tell you haven't been growing very long..just try it before you criticize it.

Jack's 20-20-20 is meant to be used with Jack's Cal/Mag product (because the all-purpose has NO Calcium) and they make a BLOOM BOOSTER that's meant to be used during flower. So here we go, back to 3 products. Not impressed. I've been growing long enough to know to give my girls Cal/Mag, so I've got that going for me.

Crazy how similar this stuff is...almost like it comes out if the same factory or something.

This is 100% bullshit. Tons of successful growers feeding this way. Theres an obvious difference between giving "Veg Nutes" in flower vs feeding a balanced nute base that has everything a plant needs at any stage of its life. 20-20-20 is not a "Veg Nute."

Also, TMK JR Peters is not owned by Scotts Miracle gro.

Jacks bloom booster is only used for the first 1-2 weeks of flower(if you even want to use it in the first place) and then it goes back to the regular 321 schedule that is used from veg thru harvest.
LucasMethod is same feed veg thru harvest.
There are several nutrient lines that just feed the same base nutrient throughout the whole grow and they all work just fine, i.e. veg+bloom

Make sure you're giving them some Calcium supplements bro. I'm not denying that you CAN grow weed with Miracle Gro all purpose, I just know for a fact that you'd grow better herb with a more dialed in nutrient regiment. 20-20-20 all throughout the plants life cycle means you're giving it a lot of stuff it doesn't need at all times. That's a lot of built up salts and waste sitting in your soil. Your girls deserve better.

I've tried the bloom and saw zero difference.. I'm not bullshitting you man.. Try the 20-20-20 start til finish.. You'll never go back. I've never supplemented cal or mag..i grow led indoors and outdoors under the sun..no greenhouse. No supplementing any bloom booster or cal or mag..just good ol jacks classic 20-20-20..

I got turned onto it on this very site almost a decade ago.
