What Deficiency Is This?

[MileHighMeds]

My plant is about 3 weeks into flowering and is showing great pistil and trichome production. Last night I noticed some sort of deficiency on a few leaves on the lower half of the plant. Can someone I.D. this deficiency and how to go about fixing it? Light cycle is 12/12

Lights: Feit electric Red Spectrum 19W LED and 2 White LED 4000K Strip Light 12W
Substrate: LECA clay balls and some fuzzy adsorbent
Nutrients: Earth Juice Bloom 0-3-1
Water: RO around 5.8-6.0 PH
Feeding cycle: every 3 days- cycling water and Nutrients

Hey Mile, the lady looks good, But growing soiless your ph needs to be pretty accurate are you using a ph pen or drops and most soiless growers try to stay about 5.8 on ph. Earth juice 0-3-1 just dont sound like it has everything your lady needs, I have never used it. Plants Grown under led will normally need extra cal-mag, I grow soiless in coco and add cal mag every feeding. You need to make sure of ph first and I will check out your nutes.

Went and checked on your nutes and they will work but you will probably end up nitrogen def and I believe you are going to need calmag also, But ph 1st

Okay great i really appreciate the help! Ive been using a liquid drop test kit on the ph but its not exactly as accurate as id like. Headed to the store to pick a PH meter and some calmag!

Again appreciate the help!

I see nitrogen toxicity and you need a bigger pot and a sativa strain with purple stems to much stress.

Hey ICHIJAVA, i dont see the nitrogen tox. am I missing something, hes not giving any nitrogen I believe ph out of wack to start with and a bigger pot wouldnt hurt.

I don't see any sign of Nitro toxicity... And the purple stems are only in the picture with the LED's turned on, so it's probably reflection.

MileHighMeds - You've got a nice looking lady. Densenug seems spot on with his advice But it's not reccomended to transplant them to a bigger pot now that they are flowering. Too much stress now (like transplanting) might cause hermie.

If it were me I would also get it up higher for more light and trim away the bottom stuff also spread it out more. But that's me.
