Please help yellowing bottom leaves making way up faster

I'm in a soil grow outdoor .week 8 veg. Gen hydro 3 part. I've done everything that I've researched all the deficiencies I can't figure out what exactly is going on I'm getting this yellowing that's going up I can folder feed and it'll look nice and the next day looks badd any suggestions thanks..you may notice some leaf burn from the heavy foiler feed when I panicked...

Most of the leaves are yellowing, I think due to lack of light. Anything low and in constant shade will yellow and fall off. I would remove any lower vegetation that is inconstant shade (lollipop it like it’s hot), this will save the plant from using up energy on lower bud sites that won’t yield in the long term anyways. Also how I get my clones for indoors. Good luck dude

A couple of points: If you foliar feed and the plant perks up but for only a day it makes me think maybe nutrient uptake is locked somehow. Make sure your ph is correct so that all nutrients make it up the plant. If you've been using synthetic nutrients for 2 months, it may be time to flush the salts away.

Second thing I see is possible white powdery mildew. Is that what the white stuff is on your leaves? WPM can be caused by high humidity or poor airflow/ventilation. See this article for help identifying and removing WPM -

Thanks for the help. The whit powder is diatomaceous earth. I'm growing in the ground so how would you recommend flushing. Gen hydro I thought was organic but I'm game for just about anything to save my babies

this is today. Her sister is below and seems to be having same issues. To opposite sides of the yard.

Your plants look fairly healthy to me!! They look decent for outdoors, I would just remove some leaves that are possibly blocking light to future bud sites. I don’t see a need to flush, there is some slight leaf curl but it looks sativa and in stretch which sometimes just happens. D/earth seems to work seen a few growers have luck with it. I have it at home use it for the chickens and horse’s keeps the bugs off em, I’ll be using it on my outdoors this year. Now it’s time to smoke a bowl
