Are you ready to play... Guess the Deficiency!

....32" was fine, I didn't say to raise them even more,... your manufacturer will have recommended distances as well,... lower the lights to where they were again at 32".... at day 24, she's overdue to start stretch anyway,... do you see presex signs yet?

So @Waira I raised the lights because you had mentioned "but those are powerful lights, watch your distances" so decided to raise them for a day or two to see if there is a lighting issue (process of elimination). They are back down to about 32" because I saw no real difference in the girls.

I do see pre-sex signs that I have a female...not to mention the seeds are autoflower and feminized so I would only expect females.

@Waira so after checking runoff PPM and pH I finally figured out what the big problem was. My runoff PPH was as high as 2900 and the pH was in the mid-7s. As a result... I decided 2 do an emergency clear water flush. After the Flash my ppm's were between 5 and 600 and the pH drops to just around 7. What I intend to do is start slowly reducing the runoff pH by slowly reducing the pH of the water / newts to the Lower Side of optimal or around 5.6. I figure that within about 2 weeks the runoff pH should be optimal.

As a result of the flush, the young lady is gaining more color and I have started doing some LST on her. She seems much happier and because of the flush yesterday I chose not to water or feed her at all today. Starting tomorrow I will start her again on quarter strength nutes and increased to full strength over the next week to 10 days.

Below are a couple pics of her today after the flush and of the LST that I'm starting. On a side note... She's growing like a weed!

Huh! I swore I asked you about how much run-off you were doing each time,... must have got you mixed up with another! Coco is not easier than soil IMO, it has a lot of do's and don't's... I'd say it's the most common problem medium I see in here, primarily because few do their homework on it and end up treating it like true soil... True, it's a common component to soils, but they have a pretty complex mix of other things that changes the whole game vs. coco,...
Anyway, 15-20% run-off each time, never water alone (that can start to screw up the CEC/Ca/Mg balance deal),...take pH and run-off ppm's going in and out; r-o should stay under 300ppm more than going in.... coco breathe super well, and this rapid cycling of nutes can potentially make for monsters even in small pots, if you're willing to grunt out the daily labor,....
Definitely a serious build-up of nute salts! frankly, I'm shocked that the leaves gave no sign of this with burn, much more severe lock-outs,... especially at 7+pH! Coco works best around 6.0,.... I'm not a coco user, but guru's say 500-700 ppm for this stage, depending on size, demand, any symptoms, etc.,..

@Waira Thanks for your reply. I am doing (as you mentioned) around 20% run-off. Since my last post the lady is looking ok yet her growth has slowed a lot. She looks fine but I suspect her growth is permanently stunted. I will continue to grow her in hopes for even a small harvest in a few months.

The biggest issue I see is that there are a lot of knowledgeable people on here that have apposing advice LOL. It really gets confusing sometimes. But, that being said; I respect all advice and opinions...all I want to do is learn and become less of a person who is asking for advice and more of a person offering and giving advice. I thank you again for the time you invested into my issue.

CANNA has a great website full of coco grow tips, etc.,... and we have some excellent coco-nuts here too, so check in on them in that forum and around generally,... coco is work, period, unless you rig a drip system or do Autopots or something similar,.... i hear you on conflicting info, so just keep such things as suggestions, and research them to see what's solid, anecdotal, or plain BS! Cheers bud!

More food more light more air.
Flood the pots at 50% pot weight look for 20% run off
Watch for fungus Gnats
You want around 1.2 to 1.5 EC whatever ppm that is around 900 pretty sure

Sounds like you are not flooding them enough...no way they should need flushing at this age if you feed them properly.
I never flush until a week before harvest.

Also never flush with just plain water when using Coco
