White widow photoperiod Feminised17 weeks in veg stage some plants look worse than others. I’m not sure if it’s a nutrient defect of too much nutrients or not enough. I us coco coir for my soil and fox farm for my nutrients in 5 gallon pots in a vivosun 4x4x8 room any help would be greatly appreciated

@1977dam welcome to the forum. Provide the info requested by @Myfriendis410 . It will help everyone diagnose what’s going on. There are a ton of variables from soil to nutes to lighting. From a glance it looks like the nutrients might be too strong? I am in coco as well and run mine about 2/3’s strength.

Do you have a ph meter and an ec/ppm meter

I see three possible scenarios causing this, first is PH , but I won’t comment until you fill out the ticket and see where you’re at and provide a little background to go off of. Please provide detailed feed/ watering info and post a close up, focused pic of your grow medium too please.

Are they 17 weeks from sprout? I would not have figured that.

Yeah just looking at the pics i would say ph lock out. You need to get a ph and tds pen and check run off

Welcome to the blog..
Agreeing with a few other as to probably PH issues..
But numbers would help…
Happy growing..

Coco-coir is a form of hydroponics and the growing “technique/style” is completely different then soil.
Heres a technique that will work.
Begin daily watering to ~10–20% runoff. Water once per day when lights turn on.
Runoff is very important in coco-coir to keep nutrient from building up.
Nutrient strength: 500-600ppm veg nutrients, pH 5.8–6.0.
Light cycle: 18/6
Once you get them shaped the way you want they are ready to flip to flower soon as they get on track and if you follow this routine, you will quickly see results.
But once you’re ready to flower.
Switch to 12/12 light schedule.
Gradually increase nutrient strength to 800ppm , depending on strain and signs of deficiency/toxicity you may increase to 900-1000ppm but typically I never go over 800ppm.
pH stays at 5.8–6.0.
Water daily, still to 10–20% runoff to avoid salt buildup.
Once you get coco-coir figured out you will love it my friend 
It’s the best way to grow

@1HappyPappy is dead on here. When I started in coco, I found they had to be fed minimum one time a day to complete saturation and good amount of runoff. I felt like I was going to drown them but they exploded and haven’t stopped, they’re 3weeks in flower and over 7 ft tall, they have been pollinated for seed crosses. Coco will grow like like no other medium, hands down, but it takes a lot more feedings to do it. I just installed Autopots on a reservoir tank.

So run off I only water when they need it and I only give them at the most 6 cups every 2 to 3 days and my pots are bags except for one of them and feed the 1 time a week sometimes every two weeks

Google search "high frequency fertigation in coco-coir " and/or search “coco for cannabis” on YouTube.
What you’re describing sounds just fine for soil but coco-coir is a different beast my freind..
Searching those key phrases and read or watch YouTube videos is extremely helpful..
Here’s what I grow in coco-coir so you can see the results.
