Newbie concerns...any thoughts?

Started my first indoor grow about 4-5 weeks ago, just have the 1 plant under a 600w LED (approx 2ft above plant), 18/6 light schedule, using a coco/perlite soil. Problem I've come across is after I transferred from a 1 gal pot to 3 gal. Not sure I transferred nicely and wondering if this is a sign of root damage, a byte issue, or am I burning her with the light?
Brand new to indoors and learning as I go.

I am under the impression that slow yellowing on the bottoms is a broad deficiency, but I am still new. Just what I remember reading. I hope some of the home grow heroes get to helping soon!

What is your feeding schedule?
It looks hungry and it's extremely small for 4-5 weeks.......looks more like 2 weeks old.

I thought the same for its age, but this being my first indoor I wasn't sure what to expect. Admittedly haven't been feeding nutes yet, still waiting for the package-have only been watering about once a week or when pot feels light

Coco is drain to waste hydroponics and should be fed to run off every day in veg and twice a day in flower.
Never plain water and never let it dry out.
These plants are 23 days from sprout and fed nutes daily to run off for a comparison.

Good luck.

Broad yellowing from the bottom up is likely nitrogen deficiency, especially if it's been 5 weeks and you havent fed her yet.

Hit her with a low dose of Alaskan fish fertilizer, or your preferred veg nutrient, and shell darken back up

Yeah I had no clue there haha, thanks for the info, hopefully things get better from here-any specific feeding schedule you can recommend?

What nutes are you using?
I suggest starting with 1/4 strength of the recommended amount, and increase from there.......feed at least once a day to run off.
I use MaxiBloom.

First grow for me also.... I’m in coco, I put 5 cups of ph water wi nutes every day and get one cup out. Done same throughout and about 5 days away from chop now... 3 plants...

You need to start feeding since there are no nutrients in coco other than some calcium used to buffer it with. Also, root damage when transplanting is not as big of an issue as some people think. Sometimes when I let plants get too rootbound before moving to a bigger container I literally tear the roots apart and spread them out so they're not all clumped up. It never shocks the plants when I do it. In fact it's a common practice with many plants when transplanting. I think those that have issues are doing something else that's causing their plants to go into shock. Most likely by dumping some product on them when they transplant.

This is what I have coming in, just shipping has been taking longer than expected

Those will work. Start out at half strength at most.

Yup, coco needs nutes from very early on. If you can get cal-mag fast, add some as it will provide some Nitrogen along with the Ca and Mg. This will help while waiting for your nutes. I agree, 1/2 strength (or even a bit less) to start with FF trio nutrients.

What you have there is a Nitrogen deficiency. Piece of cake. Your plant isn’t growing because it’s growing roots. ( which will explode within a week) providing your feeding at least 600 ppm. Shed some light on her and lower that light down 6-8 inches as long as it doesn’t burn your hand your fine. Light burn starts at top. N defincieny starts on lower leaves. (You’ll notice this in late flower). Coco growers need to also know that Mg lacks in coco coir because it’s inert. So supplement it. I use all Canna Products and still supplant with cal-mag plus. Coco is very forgiving if you use fabric pots. What exactly are you using for Veg Nutrients?

I wasn't as prepared beforehand as I should've been and am waiting for my nutes in the mail-only been feeding water, which I've learned quickly here is not enough-gonna try getting Ca/Mg asap before my nutes arrive

Can I ask you a quick follow up?
Just got my nutes in the mail and directions say to use in water every other feeding. I feed twice a day, should I do 1 feed as plain water and 1 with the nutes, or cut the dose in half and use for both feeds?

Just got my nutes in, directions say to use every other feeding, I feed twice a day, should I feed once with plain water & once with nutes or split the dose and use nutes for both feeds?
Thanks for any help

In coco, you're better off not feeding plain water. See the website posted by @MickFoster to learn why - www.cocoforcannabis.com. Don't forget, start FF nutrients at a lower strength than the feed charts tell you, maybe 1/4 to 1/2 strength and adjust based on how the plants react.
