First coco grow

[Greenthumbgrower1986]

Hi all currently on my first photoperiod plant in coco(usually autos in soil). Just wanted to get someone's opinion on this girl, she looks a little light. She is 12 days old in ecothrive coco with charge. She had plain tap water days 1-7(230ppm 5.9ph) then moved to 0.6ml per litre of shogun A +B and 0.5ml per litre of shogun silicon(397ppm 5.9ph) been watering every 2 to 3 days, she was moved up a pot size 2 days ago as her roots were hanging out of the bottom of the pot. Temps are 25°c rh 55%

In coco u want to water everyday til decent runoff. Also every watering should have nutes. I never water with just water it’s always nute solution. I start seedlings around 300-350 ppm and go up every week or so about 100-150 ppm. Usually by week 4 I’m at 800 ppm and usually never go over 900 ppm or so.

even when the plant is small still water to run off? . I didn't add nutes to start as ppm of tap water is around the 300ppm mark and already high in calcium

Feed to run off daily.
Never plain water.
Never let the coco get dry.

When I did this originally she was showing signs of overwatering

 

[Greenthumbgrower1986]

So I reduced amount of water but still slightly droopy. Since day 7 she has had nutes every water

Impossible to over water in coco unless it's a very small plant in a very big container. Coco holds 30% oxygen even when completely saturated. Perlite helps with aeration.......you might consider adding it next time, or when you transplant.
I feed daily to run off from sprout in veg and twice a day in flower.

 

[Greenthumbgrower1986]

So maybe drooping due to being underwatered

 

[MickFoster]

I find that for the first few weeks, most plants get a little droopy at times........especially just before lights out.
These plants are 2 weeks from sprout......you can see they're a bit droopy.

This is 4 days later.......18 days from sprout.

she looks stressed honestly... i think there's a problem in the root zone, coco is sometimes dirty or salty.

Did you prewash the coco?
Why not coco/perlite? Coco by itself has never been a good solution for me. But with 30/40% perlite its bomb

also pure coco stays so wet that is a magnet for gnats, maybe you can't overwater a flowering plant thats full fledged drinking a gallon a day, but a small clone? i've put 500ml of solution into small pots and had clones be sad for days..

I did origanlly start with coco perlite in 1 pot and plain coco in the other and the one with perlite took longer to dry. This is her roots

 

[Greenthumbgrower1986]

No didn't wash coco as it's pre buffered

The coco used by the OP is rinsed and pre-charged.......can be used straight out of the bag.

Most quality coco nowadays needs no charging, rinsing or buffering.

If there is perlite in there.......it's not much. I prefer a 70/30 coco/perlite mix.

What should my next steps be then. I'm close to throwing it and starting again in soil

No reason to throw it out.......your plants aren't that bad. Coco is simple.
Start feeding with low nutes to substantial run off at a pH around 6.0.
Feed daily, never plain water, and never let the coco get dry.

What size pots are those?

1.5litre

Consider transplanting in another week or less......in the meantime, feed everyday to run off.
What is your final pot size?
