What's wrong with my plant

[simon836]

Hey, been reading a while and I've started my first grow. I have 3 autos that have been flowering for about 10 days. 2 of them look fine, but one is stunted in growth and is barely doing anything. They are being grown in 11l pots with coco under a magnum led. Feeding dutchpro bloom nutes with a small amount of big bud. Here's the photos and help would be appreciated.

Welcome to AFN! Not sure what you did or didn't do, but not seeing any pictures posted.

Usually the biggest cause of problems is incorrect pH so that's the place to start. What is the pH of your nutrient solution and the pH of your run off?

Okay, seeing your pics now. You need to remove them from under the LEDs and take the pics in natural light so we can see the true color of the leaves.

How high above the plants do you have your light set?

Sorry about that. Just took some new ones. I don't know which strain it is, but it is either onyx, blue himalaya, bubbleicious or hindu kush all auto.

They are probably about 1 /12 to 2 feet away from the light right now

Okay, that's a good height on the light. What about your pH?

ph is 5.7 run off is around 5.8-5.9

5.8 5.9 is on the low end for soil grows. Might try bumping it up on their next watering... Proper ph for soil is 5.8 to 6.5 with optimal being 6.0 to 6.3

But good Ol Muddy will get ya where ya need to be...

Merry Christmas Eve....:thumbs:

Since you are growing in coco, which is a soil less medium, that pH isn't too bad. A hair low but certainly not enough to cause a pH related nutrient lockout. Your plants look healthy. Maybe a little leaf tip curl but nothing severe. That one plant could just be a runt. Autos, being relatively new, aren't fully stabilized yet and runts are fairly common.

ph is 5.7 run off is around 5.8-5.9

Can you post a picture of just the stunted one so we can get a closer look at it?
