Do these look ok?
Quite normal for the new grouth to be lighter green. If it all over the plant watch it, if just on new grouth should be ok.
The more I look at yours the less I think this may be the same thing. Need more picts of intire plant.

Definitely more pictures. But on the right plant we got an old fan leaf light green. So it’s not just new growth. Looks like iron def to me. What are you using for nutrients? Are you using ro/di water? Definitely looks iron to me. @dbrn32 @AfgVet @PurpNGold74 @Covertgrower @Myfriendis410

The lime green in new growth,for me anyway, has always came from the center. So it goes dark last. Not the case here. Why I would wonder about iron.

Using fox farm with distilled water.

Like to see some ph and TDs readings. Especially if that’s FF soil. How old is she?

You need calmag in that distilled water. I use happy frog and ILGM nutrients. I zero filter under 15ppm. If I don’t use calmag on non feed days, I quickly run into iron issues. Easy to fix at least.

Not foxfarm soil, just a mix of potting soil and dirt. Turn it over every year, have good drainage, I just bent the plant over to stress it a couple days ago

Nope. Dolomite lime has some kinda micronutes but im not thinking its a calmag supplement. Epsom salt is a good mag one. Boiled bones are a good calcium supp.
Dolomite lime is a great ph buffer for lower pH

Dolomite lime can provide calcium and magnesium, but it’s definitely not same thing as calmag.
For a soil to be iron deficient isn’t all that common. I would suspect a handful of other issues before throwing more iron at plants. Ph, locked out by too much phosphorus, or maybe soil compaction or root bound. If that is indeed the issue here, I would look there first.

Very informative! I just hit them with the recommended fox farm, grow big and big bloom on Friday. No issues up till then. Thinking maybe too much ferts , caused a lock out of cal/mag. Thinking about flushing. This is also first year mixing nutes with distilled water.
Think, too much fox farm, followed directions on bottle, no water in between feeding, some kind of lockout, thanks for your help
Hopefully you are using a TDS meter and setting the concentration to no more than 1,100 ppm.

I keep it simple, lol, growing a long time on and off. Second time using fox farm. Used the recommended on bottle. Watered full strength, only took a half gallon. Topped off to make a gallon of half strength. Watered with that 5 days later. 6 days later water with full strength again. 2 days after that I notice the light leaves. All good up to now, used half strength last year with no problems, think I over did it, going to flush with water and wait a week
