Help deficiency/toxicty week 5 flower

I am currently in end of week 4 start of week 5 flowering.in soil in 30l pots.have bearly feed any nutes under 2 600w hps.just got on top of all problems and now this started happening to the leaves on 1 of the plants.anyone have any ideas will upload better pics tonight and whole plant pics

Pics of the whole plant. Where were these leaves? You say you've had problems. Like what? What medium they're in?

You're in mid flower, you say you hardly fed? If that's the case, then you are looking at a deficiency, not a toxicity. That issue, is clearly a lack of phosphorus, nothing to do with your lighting!

Will get pics of whole plant tonight when they go on.and every time i go to feed it seems like the plant is getting locked out.checkd my runoff ppm and it is ranging bewteen 600-1000with just watering does that seem normal to you guys?this is 1st time using 1 hav done 4 previous grows with no problems and great yeilds just under 1 pound a light.im thinking it may be my soil causing probems as it has slow release nutes have used it before with no probs tho

what ph are you feeding at?

6.5 ph seems ok

.

Any ideas? Only seems to be happening on the 1 plant out of 7.well at the moment anyway

Thats right, next time use coco/perlite so you control how much feed goes in with hydro flowering nutes and the last 2 weeks a bloom booster. The soil is causing the early yellowing probably from salt build up.

Yeanim going to flush tonight wont be using soil again

have bearly feed any nutes

this is part of the problem feed water water feed. Are you adding any microbes to your soil. is that a no, then a pinch a week would help tons.

Looked at your pics they dont look bad at all maybe a little potassium deficincy on some of the leaves the other spots idk about.
I wouldnt flush just get on a feed water water feed stop checking runoff cuz that is muddling your brain. Maybe do one heavy flush mid flower to wash any heavy salts out renute with microbes. Microbes will handle most of the work for you as far as ph and getting what the plant wants when it wants it.

Stick to soil no need to change it up cuz somebody said so. Coco is different and if you cant handle soil you cant handle coco. Dirt is good mmmmkay.

Feed it with some microbes and your golden.

Go on the yutub and watch all the plant nutrition videos you can find start learning about that. learn what humic acid is/does and microbes, kelp, amino acid etc each one put it all together in the brain.

Study nutrient companies feed charts what are they using why do they say add this at that time stop adding that at, at this time, read their labels. There all kind of similar. Figure out what the plant wants when it wants it.
