The morning after every feed with auroras flowerin...

Brother your plant is looking healthy! Don't worry about it... in case you are not using a ppm pen to measure your water ppm and make sure you are on the right levels for your plant stage. You can also download feeding schedules with the recommended ppm levels. I hope this helps

Your plant sure looks nice. I've seen and read about many plants as they go into flowering and harvest that slowly the leaves will naturally yellow off and somewhat die. I don't know if this is your cause or if there's a higher nitrogen content than needed at this stage. But since you're playin it safe and doing light doses, it may not be nutes at all.

No need to worry if yellowing process is soft and just for the bottom leaves. In Flowering plant push N from the bottom the the flowers.

For the most part it is looking very healthy. I would probably flush it for a 24-48 period then reintroduce nutrients. If the issue persists then you could try lowering your nutrient levels from 1/2 to 1/4. Make sure that you are testing your Total Disolved Solids before and after adding nutrients. Once from your watering can or container and then again from the runoff that comes out the bottom of the pot. If your TDS Meter reads above 400ppm you could be drying out your grow media with too much salt. Hope this helps.

Bottom leaves will go yellow and brown and fall off I would be more worried if it was the top of the plant , tips of leaves will go brown if there is too much nutrients , having said that she is only little so she won’t need a lot 👍

Dude and Athos are right about lowering nutes or using none. It looks like you have a nutrient lockout caused by excess nutrients. Try a flush with less than half of what youre using right now.

That yellowing (or chlorosis as it's called) if you take a closer look its not homogeneous, but between the leaf veins. Interveinal chlorosis is a classic sign of mg deficiency, As you are using RO water you should give them some Ca/Mg additive. Also 35 ml / lt of feeding? I think you are going to burn them, get a EC/PPM meter and measure you feeding strength, I'm sure it's a bit high.

I’d back down farther on the nutes or try water only for a while.

Try a tbl spoon of Epsom salts in warm water (to dissolve salts ) cool and water it well if it mg deficiency it should clear it up. Check your nutes to see if they have mg in them. Might need a cal mag or something similar . hope this helps.🙏
