Hi guys, just wondering if anyone can tell me why this is happening to the edge of the leaves of my one plant . All the tips are yellowed ? Is it too close to the light?
Why is this happening ?

Hiw old is she? What soil are you in. Are you feeding her yet and what light is she under?

Are you measuring your EC going in? pH as well.

I looks like nute burn to me. What ppm are you feeding at. That young I would feed 100 to 200 ppm once a day and water as necessary being in coco. Maybe someone else will agree or correct me if im wrong.

Yes I would ph to 5.9 - 6.0

I am ph'ing the water. I mix 1 gallon of nutrition at a time according to the charts on bottle and then feed the plants as much as they need from the gallon jug

I would keep doing the same. Feed until runoff, daily.
If you're overfeeding, it's only very little.
Keep on feeding until runoff.
Dilute feed with a little water, if you find it's too much, or it starts getting worse.
Keep trucking on.
Recommend getting an EC meter. Removes the guesswork.
Feed chart should have EC values, though.
Having an EC meter allows you to easily dilute to desired value.
It's a useful tool for other instances too.
Even if you don't use it often, it's good to have one.

I also use GH and coco (50/50 coco & perlite). I agree with the others about getting a TDS or EC meter. The "Aha" moment for me was when I started thinking about the feed mix and TDS separately. I personally mix up the mixture at about a 2:1 ratio (so 4 gallons of mix in 2 gallons of water), then I add more water until I get to the TDS I want. I follow the GH weekly 6-part medium feed chart almost exactly and I stay towards the bottom & middle TDS range for each week. This has worked well for me in my setup.
When my plants are seedlings I grow them in solo cups before I transplant them to 5 gallon AutoPots. While in solo cups, I water them daily using medium feed week 1 @ 250 TDS. With coco and perlite I've never had concerns about them drowning. It's just the opposite for me - I have to water/feed them daily because the liquid just pours right through.
