Lime green to yellow leaves early flower

Hello everyone! I try to research things before posting but I have to admit I’m at a dead end with this one...I have grown from soil to coco and now to organic. No matter the medium seems that I end up with yellowing leaves early.

Currently I use a local organic soil comes amended with lobster shell And composted manure and ph balanced. I mix a total of 10 gallons with My own EWC with perlite and some coco coir.
Then I amend with a half cup of the following:

Kelp Meal
Alfalfa meal
Neem Meal
Crab Meal
Dolomite Lime
Bone Meal
Blood Meal
Epsom Salt

Also the following:
2 Cups glacier rock dust
1 Cup Gypsum
1 Cup Oyster Shell Flower

I let it cook for around 30 days if not longer. I also use RO water with CALMAG. The plants seem to do great for about 5-6 weeks and look beautiful and lush Then like the 2nd-3rd week of flower they Start turning light or lime green.

I have also been making teas with Neptune’s fish fertilizer kelp molasses and EWC and feeding every 10 days or so during flower. Nothing has helped and not sure what I am missing.
The pic is a blue dream in her second week of flower. You can see how the leaves are starting to lighten. I just

Any help would greatly be appreciated. Thank you all and I look forward to your responses!

Not a pro. But home mix organics. Appears to me your missing N in your mix. And possibly some carbs I'd suggest a water soluble organic fert. But would suggest trying tap water for a few days. R.O. throws my grows out of balance. You could also try lowering your water PH to allow more N uptake. The blood meal should be pretty warm in your mix. Not digging in it. Just speculating. Thoughts anyways.

Thanks for reply MIchi, I have tried the tap water no improvement. I stay away from it due to the chlorine and chloramine that kills microbes. My ph is at 7, the dolomite lime neutralizes so I don't think that's the problem. Maybe swap guano for the blood and bone meal idk. Thanks again.

Just talking on the fly. But I use PH to correct my potted plants minor issues. It isn't full organic in a pot. Nature is removed. Drop your ph to 6.2 -6.6 and get a good run off. Fixes my nute dips in a day or two. My way. Might be useful. Again just knowledge to ponder. Peace.

Try a couple of feeds of fish emulsion

An occasional soaking of clorine in tap water is actually beneficial for bad microbe and fungi control. Not mortal to bennies. And the trace elements are good.

What do you use to correct the ph? I have ph down but from what I understand it’s a chemical and bad for microbes. Thanks again!

Thanks for the reply! I did give it a tea with Neptune’s harvest Fish feet about a couple of days ago and have not seen a difference. I’ll post another pic when lights come on. Thank you!

I will give it a shot thanks again appreciate it bro

Another thought should I replace the blood and bone meal With guano? I’ve read good and bad on both.

I forgot to mention a few days ago I did too dress with gypsum Kelp and fish bone meal And covered with EWC under mulch. not sure if it will do anything.

So here’s a pic of her in week 4 tried to get the best pics I could. Thanks again.

What cal mg product? I was having similar issues with ro and cal mg. Ended up switching to a low boy filter. And big difference compared
To ro.

2nd week off flower topdress 1 cup off bloom topdress with 2 cup off your worm casting i use gaia green 284 premix ammendment

I topdress every 3 week.

Your girls are hungry.

I’m super new but very interested in this topic. Do you need the added cal mag in your water if you are using dolomite lime which has cal mag? Thinking nitrogen issue as I have read that you should slowly decrease nitrogen in the first couple of weeks not remove it altogether when starting flower. Thoughts?

Look up Gaia Green or Dr Earth.There both dry slow release organic fertilizer.

to me and I'm no expert by any means..lol
it looks like your lacking in N for some reason, either not enough in your mix to take you through the whole grow or its being locked out by something. I'm thinking not enough for the stretch
i find my plants need more N in early flower for the stretch, so I will top dress at the beginning of flower with either Gaia green all purpose 4-4-4 if i think it might be lacking in N or a mix of 50\50 all purpose / power bloom everything else. This last round i misread my plants and should have given three of my plants the 4-4-4 instead of the 50\50 mix as they ran out of N and ended up looking terrible compared to the rest
so i topdress the above mix at beginning of flower then at 2-4 and sometimes 6 weeks top dress with power bloom
maybe try giving them N at the start of flower for the 2-3 week stretch and then top dress with your bloom ferts at 2 weeks and as needed
