Everything was fine until flowering started early stages. My leaves on started burning tips, I backed off my light from 18" and went to 24". If you look closely at leaves tips newer growth has burns. I’m using gaia green organic in my 70/30 coco/perl mix.

Newbie myself. Plants look healthy to me. I believe tips on leaves is described as lady fingers. Means nutrients are right. Try searching for “lady fingers” and see if you agree.

Plants are looking good! I seriously doubt it’s light burn. That’s probably just a little extra nutes no big deal unless it continues further down the leaves a lot. When cannabis intakes to much nutrients it pushes the excess to the tips of the leaves. I have had light burn it can look a few different ways. Most common is the edges and tip will yellow or brown. I’ve had one that looked almost identical to calcium deficiency. You can get white buds or leaves. I’ve also had one that the middle of the leaves had stripes of burn outside of the veins. You’re doin great for a newbie my first grows back 15 years ago never looked that good 
. Keep it up!

Also if you don’t already I’d highly suggest measuring your ppms. You can get a ppm meter cheap on Amazon. Do a run off test. If you don’t understand watch a YouTube video on how to measure soil ppms and learn the appropriate ranges for each stage of growth. Gaia greens great stuff especially for beginners learning. Minimizes alot of work to.

She looks fine little leaf tip burn. I like running mine with little burn. Means I’m pushing her to her max.

They look great, No real worry unless it persist.
What strain are you running at the moment?
Only reason I ask, they look indica dominant in leaf growth, which would lend to the fact that at veg stage they require more nitrogen for that stage and flipping to flower ( if nitrogen is still heavily available) the burn may be coming from the plant searching for particular nutrients and instead finding nitrogen first.
I would run straight water for the next two feedings ( depending on soil make up I.e.: coco coir heavy, perlite heavy, straight gardening soil) to see if your pH is staying within your parameters.
If you find everything stays on point, you should be all set.
Happy growing and enjoy the bless.

New myself, isn’t or does the edges of the leaf start to “alligator” up to show signs the light is to low or turned up too much a first warning sign of heat stress?

They look absolutely nice and healthy. No need to worry much.

I used to believe that same thing because I read it in so many places over the years, but it turned out that’s just another bro science false fact.
This is from the Coco for Cannabis website. More specifically, the “understanding osmosis and EC” tutorial. It’s a great website for information, even if you’re not growing in coco.

A bit of tip burn imo is a good thing. Seeing the biggest finger with less then a centimeter of burn means ur maximizing her feeds. Seeing all the serrated tips burnt or clawing means you are in excess to the point of it being detrimental.
Light burn is seeing the tops discolor. Closest leaves to the light begin to look bleached and it spread downward over exposure/time.
Your plants look happy and healthy. No worries there.
Never knew that about the reverse osmosis making the water harder to intake tho @Cap_Ron good bit of info

Dang that’s pretty cool I appreciate that! Yea I tell people all the time you can learn from anything whether you’re in hydro soil or coco. It’s the same plant with same needs. Just some methods are a tiny different like water requirements ways it absorbs oxygen etc

Yea it sounds like when ur Vpd is off in a way what he’s talking about. Side note saw ur a ravens fan. Baltimore born n raised here!!!

Haha! Go Ravens! Been down since the day I saw Ray Lewis remove Eddie George’s soul thru his kneecaps. Like that’s my fav running back ever. Definition of a BEAST. Ray took him, bent him over, and just kept on going. I looked into the team and saw ‘murder and dope charges’ and from that moment forward? Purple and Gold all day.
VPD imbalances are super noticeable. Depending on being over or under the chart screams at you. Like ‘What’s wrong with her?!?!’ Screams.
Those ladies look great. Just a few minor what’s this? Kinda questions

Just an FYI here from another 1st timer. Thankfully it seems you have not burnt them up. However, I did mine in their early days and while they have fought back they are small and have been in veggie state for quite a while now hoping they will get larger.
Anyways, my point of being here is to say that light burn doesn’t only happen due to having the light too close. It can also happen by having the light turned up to a higher intensity than is needed.
So there’s that for us all to study up on too.

Thank you everyone. I run straight ph 6.5 water for feeding and just top dressed this last weekend with flower mix from gaia dry. I’m just trying to be perfect on my first grow hahaha. I’m just gonna run it how it is. Thanks again

It’s slow release nutrients mixed originally and then top dressed last weekend with gaia green organics. I water everytime with just water pH to 6.5. But you are correct front and back right are indica Dom and back left is sativa Dom. All started same day and both have the “same” grow times on the site purchased from.
