Newbie here. Posted a pic of each plant. Transplanted 10 days ago (from quart sized pot to 2 gallon pot, probably to big of a jump.) May have watered/fed too much. Using H3ad's 6/9 formula in 60/40 coco/perlite under CFLs.

What do they say? Keep It Simple Stupid. Not saying you are stupid.
Growing on Coco/perlite? Heads 6/9 formula, whatever that is.
Dude, don't over complicate things.
They are plants, they are meant to be grown in soil, that's what they have been doing for thousands of years. So why suddenly think you know better and try to change it to an un-natural environment?
Ok, these ones of mine are grown in soil; store bought potting soil with some perlite mixed in for aerations, and a bit of lime to raise the PH.
Fertilizers; just common garden water soluble fertilizers from the supermarket.
Well they look a lot better than yours, so I don't want to pick on you but don't over finesse, keep is simple.

Your Ph is off, judging by colour of stems and leaves, and your stated mix I'm going to guess its high.... Best to feed at a ph of 5.5-6.2 EC 1.2-2 immediately and only about 500mL, do this every day for 4 days then take a day off and then water or enzyme.
Coco perlite has no "food" and a high relative Ph, you need to feed often and run your ph lower until you can feed to run off without bogging down your roots. I like 4 small feeds to saturate the medium then day off to dry out, on the 4th day the bottom should just get wet, but after day off shouldn't be too dark. Up mL by 100 and repeat.

So you're comparing an experienced growers soil grow to my very first grow ever in coco? Get lost.

@rykus and @iTarzan I think that's probably it, don't know why I didn't think of that. When I got them I didn't have any nutes or ph meter or anything so I was just watering with my tap water (when I finally got my meter it pH'd the water at 7.3). Had the small amount of pH down that came with my meter, the bottles I ordered come in the morning so should I do a bit of "over correcting" and go for the low end of that range, like 5.5?
Also, I'd been wondering how to feed enough without overwatering, now that you suggest the smaller feedings that makes sense. Wasn't giving them tons before, but probably around 700mls. Thanks for the help.

Yeah, that makes sense. Always remember, this type of soilless is essentially full hydro style with just the safety of a higher water-air ratio, best growth happens at say 30-50% moist so while right now there is not as much root demands and no excess salt built up that could affect nutrient range, better to water only 10-25% of overall pot capacity. So your 2 gal 500ml is great, and won't over saturate your medium.
When you plant can drink more you'll want to figure out exactly how much water your medium will hold before run out and how fast your plant can drink that to figure out a good feed/flush system.
I prefer to feed aggressively with no run off then do a few low EC with enzymes on a 10 day cycle or so, but if you have good drains set up I've seen people do very well running lower EC and doing 10-30% run off with less flushing.
Also agree with Itarzan, no need to go extreme, just be consistent and logical. The plant only see's a few things and most people's main failings as care takers is consistency, that's what plants love, nice easy stress free and consistent!

Get over to the coco subforum. You'll get a lot fewer braindead style thinking "change your medium" answers.
Consistency is key with coir. Never give plain water, always pH and water by EC (unless you know your water quality and follow a proven recipe to the bloody T).

Didn't realize I could post questions there, thanks. I haven't gotten an EC meter yet. When I do, how do I adjust the EC?

You adjust the ec by lowering the amount of your fertilizers. Example: say you have a three part fertilizer and it says to give 6 tsp of A. 4 tsp of B. And 1 tsp of C. Per gallon.
When you mix up your gallon and check the ec of the solution and it comes out too 1200 ppm or 2.4 EC. This is say too hot for your veg plants.
What you do and keep in mind if you are using store bought brands you need to keep the ratios to each other the same.
Now say you need 1.2 EC ( the ec for coco from start to finish from what most say.) To get there with your A B C FERT LINE roughly you just cut the ratios on half.
Part A would be 3 tsp per gallon.
Part B would be 2 tsp per gallon.
And part C would be .5 tsp per gallon. Equalling roughly 1.2 ec.
Now granted remember that ph up/down will up the ec. And always keep your ratios constant when using a company's fert line.
This is roughly how it goes. There are other factors that come into play like hardness of water etc.
Sorry if this comes out weird I'm on a phone and I tried to keep things separate foe ease of reading.

Mikell,
I thought we lost you. Howdy.
Underveggies,
Water/feed to about 20% runoff. When runoff is finished, pick up the container, and get a feel for how much it weighs. Water again to 20% runoff when you pick up the pot and can tell it is considerably lighter. Good luck. -granger

I agree with some of the info on here, obv there are different ways to skin a cat. One thing i will completely disagree with is DO NOT feed them to runoff right now, they are not big enough and you have just transplanted them. If you do this you will have a soaking wet medium for probably a week and you will see very slow growth. They need a few semi dry/wet cycles with small waterings to get them going. And when i say small im talking like 250ml per watering. They will bounce back way quicker this way. I would ph to 6.2 and keep it there. Also pick yourself up a ppm pen so you know how much your feeding them, they need it. Also there is absolutely nothing wrong with giving plain water after a few feeds as long as its close to the ph range your feeding with. I do half a rez of water after every 55 gallon feed rez.
A qt. to 2 gal is not too big of a jump. I usually go from 16 oz cups to 3 gal w/20% perlite. I have gone from 9 oz cups to 3 gal. No problems. If you just give small amounts of water/feed, you're not wetting the entire medium so roots won't expand into dry medium. Most people water coco at least daily, many, multi times per day. What I suggested wets the entire medium, then allows it to get dryer day by day. This is how Canna recommends watering 100% coco. He's got 40% perlite. The medium won't be too wet, and it will dry quickly. Roots will expand quickly into all of the medium. -granger
Heyo,
Worked out of town for awhile in the stix re: no intranet. No more, the boss was kind enough to talk his way out of a fat contract..
Each nutrient line will have specific PH point from one medium (hydro/coco/coil, ect.) mix to the next.
If you are growing in rock wool (it's been a long time since I've used rock wool) you want the lower PH range 5.5 to about 5.9
For coco I'd go with 6.2 as the center of my PH range.
