Ok so I woke up today and noticed my plant has some leafs that are looking really ruff and some new ones starting to look bad too does anyone have a ideal what this is. I gave some nutrients about 2 days ago but it was not much and my other plants of the same strain look amazing with no problems. I am growing in soil using Flora bloom and Micro
What's wrong with my girls

This is pH problem. Did you take pH reading before watering your plants and of collected run-off?
Yeah I make sure my ph is between 6.2-6.8 I just flushed it about 4 days ago than waited two days and gave nutrients I will water today just to test run off

You shouldn't flush when growing in soil, you disturbing natural processes. Don't water it until 2 inches of your soil will be dry, or when your pot is light on lift. If you want to test your soil pH just take some soil sample (handful) and soak it in 7 pH water for 24 hours, than take pH readings.
Reduce the amount of nutrients you giving, keep your pH at 6.5 and you should be good.
Ok I believe you are right I just tested the run off and I am at a 5.0 maybe a little lower it was really orange and it should be a green brown so what should I do to get it back to a 6.5

most base NPK nutrients lower the pH, what do you use, to bring the pH up?
I use Flora grow Flora bloom and Flora micro. I have nothing to bring ph up or down other than ph up and down but nothing in the soil or coco it is mostly coco mixed with about 15-20% dirt and perlite thanks for the help

Oh that changes everything,why would you mix soil and coco, it's two different types of growing medium require different pH. Coco is 5.5-6.3, Soil - 6.3-6.8. In coco you need to water a lot more often.
For this case, I would use liquid silicon to raise the pH. Follow the schedule (Day 1 feed, day 2 nothing, day 3 plain water, day 4 nothing) always have about 10% run-off and keep your pH at 6.5 until your run-off pH will reach pH 6, than feed and water at pH 6
No I am following the directions for soil that they have on there web site the Flora series is for both hydro and soil from what I was told by GH and many others that was the most recommend to use for soil or hydro. I mixed coco and soil together thinking it would help with draining and it does but all my other girls and in just good soil mixed with compost and they are looking so good. I mean this one looks good just a few leafs are starting to do whatever they are doing. I will never use coco and soil mix again lol. I was told to use dolomite lime and sprinkle a little on the top inch to two inches of soil and that would correct it I was also told to just water with a higher ph and that will bring it up. It is at about a low 5 I would say almost 4.9 but the hole life it has been at 6.3-6.5 with no problems but I switched to flower nutes and bam I have a problem

I wouldn't advice to use dolomite lime, it will overdose calcium and mess up pH. Liquid silicone is good enough to correct low pH, it's a slow process though, you cant't correct it in one day regardless of how much water you throw in the pot.
Alright cool so I'm going to get some of that liquid silicone what happens in a couple days

what I was trying to say is that coco should be lower pH vs soil being higher pH. GH can be used for anything. with the pH being too high or too low, you will lock-out certain nutrients. if you search for a pH chart for soil vs hydro, you'll see what I'm talking about.
sounds like you are on the right track to fixing it. good luck.
Yeah I have been Google the hell out of everything I can think of for help thanks for your help as well. I could not find the liquid silicone so I got the dolomite lime and added 150 pebbles to the top 2 inches of soil and watered we will see how it goes over the next week thanks for everything

Yes Dyna gro protekt is liquid silicon. It strengthening the plant stems and is the best pH up solution.
In coco, run-off won't hurt the plant, it will just cost you more, 10% run-off is enough

Fed,feed,feed is a risk of salts build-up, this is why feed,water,feed is better in coco
That's how I do it is feed water water feed. It is my first grow and I was seen what gave me the best results and which one was the easiest to maintain and so far compost soil is the best. The plants I have in that are so much bigger with crazy tops coming in all over the place the only one that is have a little problem is the coco. I will stick to the compost soil for the next time and maybe after a few grows I will try again with the coco or even hydro.here is a pic please let me know what you think and if you think I'll be ok with the little dolomite lime I used. I used like 150-250 little pebbles

Your plants look healthy!! I still think dolomite lime is bad idea, especially in this amounts, 150-250 pebbles sound like allot. It will stick to your medium and slowly enrich your medium with calcium and magnesium, also at some point it may bring you medium to alkaline pH level. In any case, making mistakes is the best way to learn how to grow cannabis.
