Could use some help

First time growing, everything seemed to be going alright until some yellowing appeared on a couple leaves. I tried to diagnose the problem myself, but my lack of experience isn't helping much. The plant is about 6 weeks old, and this problem has been going on for at least 3 weeks now. All I've tried to do so far is to flush and add cal mag, but no change so far.

I don't know what strain this is, it's just something I found in some bud I picked up. Wanting to grow, I decided to experiment with a random seed rather than pay for better and potentially screw it all up. Included below is some other information that should help, if more is needed just ask.

Setup: ebb & flow
Media: hydroton
pH: 5.9 - 6.2
ppm: 720 - 800
Temp: 65-80f
RH: 30-45%
Res temp: 65-75f
Light: 600w LED, 24" from top

I also included a picture of a fan leaf that seems to be falling apart, no idea as to why.

dont worry about that ripped leaf, unless more appear .
what nutrient line are you using? following directions? any additives besides cal mag once and a only one flush?

I'm using gh flora, following the Lucas formula. I started feeding her some recharge 3 days ago by slowly pouring the recommended dosage around the base of the plant, other than that no additives. As of now I have only flushed once with pH adjusted water. I forgot to mention that I use distilled water also.

There has been one more leaf that was ripped, but it was at the base of the plant and wasn't getting much light, so I snipped it off.

there you go, if its not on there then pests

do you have a break down of your ppm?
like how many part N, P,K etc. honestly might be start of a K deficiency. Boil 4 bananas(peels) in 1 liter of water bring to boil, mix one part banana good to two parts water, feed

How would one go about getting a break down of the ppm? Should I pour the solution around the base of the plant, like I'm doing with the recharge?

Thank you for the help, greatly appreciated.

its easier to calculate the ppm of raw materials but you have to base it off the ppm of your feed nutes against your water, if not using r/o add about 200ppm that will consist of calcium and other trace elements. Always remember to at least aerate your water to remove unwanted contaminants that your tap water will contain. no, use your ebb and flow but maybe short soak times with more frequent intervals. but remember less is more, i mean you can have high ppm 1600-2200 but you must have experience with the perfect feeds for that plant or else you will definitely burn and ruin/kill your plant

on the back of the nutrient bottles you wil see % of amount of solution, ppm stands for particles per million. you will then have to calculate that verse the amount of water in your res then you can check those after each feed to see what amount your plants are taking and can use that data to create a killer program. growing can be as easy or advanced as you want it to be.

lucas formula? what advantage does this have over the instructions on the GH system? I've used the system per directions
and cant say one bad thing about it, it was easy, cheap and functioned well.
I would guess any issues you have using GH are the result of not following the directions maybe.

Well unfortunately, today I noticed that one of the leaves on some new growth appears to have been eaten! I can't find any signs of bugs on the leaves nor do I see anything flying or crawling around the tent...my poor lady. I've attached a picture below.

That sounds complex for a first time grower, or it's the fact I'm not great with math lol. Though it would be nice knowing my plants inside and out.

No advantages that I know of, it just seemed like a simple method but I have been giving thought to using all 3 parts of the gh line.

While I was looking into some information on pests, I stumbled upon a site talking about mosaic disease. I see some of the symptoms it can cause on my plant. Which are the yellowing/pale leaves, shiny/waxy spots, random parts of leaves disappearing as if pest damage and some deformed new growth.

Is it possible this could be my problem? If so, should I just pull this plant and start over?

TMV envy , sorry, it's never tobacco mosaic disease.

its more like "put x amount of nutrients into x amount of water. thats it, easy peasy. with a quality ppm meter you'll be able to verify the awesome instructions included with every bottle. no tricks, no short cuts.
its difficult to determine a grow issue when only some of the nutrient program was utilized while nutrient directions are ignored.

I think you can save these with some love

^ I agree.

Lots of love to give . Today after work I'm going to change the res, and use all 3 parts. I bought them all initially, but just didn't use the gro .

Do you think flushing before each res change is excessive?

well, sorta. I loved my flood drain for years, and before every change out(7 reservoirs, 20-55 gallons) I watered each plant with some plain water. flush? yeah, I guess thats what that was.....

nothing wrong with Lucas at all. I've used it for many years. are you at full strength 8/16?

saves money cause you don't have to buy Grow. Micro has all the N you need.

yes, that's what's causing the N deficiency I think.

Yes, I'm currently at 8/16. pH has been consistent, ppms started to rise recently but I topped off with pH adjusted water and it came back down to the usual 720 range.

As of now, I've only flushed once. I read that flushing could shock the plants by rinsing away the nutrients so I've been hesitant to make it part of my regimen.
