Poor leave formation. Poor veg !

[Zack]

Hey there farmers how are you guys?? Hows the work coming along? Need ya all to have a look into the pictures i am posting.
HELP ME UNDERSTAND WHAT COULD BE LEADING TO SUCH POOR LEAVES.. ITS PRETTY BAD. WHAT COULD I BE DOING WRONG WHICH IS NOT LEADING TO HEALTHY FULLY OPEN BIG GIGANCTIC LEAVES.
GROWING GREEN CRACK
SPECIAL KUSH
GULLOTINE.
Growing outdoors for the whole day which is around 8 to 10 hours then supplement the plants with 400 MH for 6 to 9 hours.
Growing medium is Mix of coco and cow dung.
nutes are bio bizz.
so basically my temperature is around max 28°C in the day and at night it falls to 12°.
Humidity is not even stable as well.
SO WHAT CAN BE GOING WRONG LEADING TO THIS GROWTH.

Did you compost the poo? Cow Doo has quite a bit of ammonia and other nasty stuff. It either needs a good leech or to be composted for a while. It does look like they are burning up a bit.

That's one reason I always recommend 100% coco to new growers. You have no idea what the soils, or amendments are doing in the root zone.

Hello Zack,
Iv been looking at your plants for 36 hrs and by the pictures I would suspect nitrogen deficiency or root/ph problem, but by the tips and the fact your in poo I'm keep second guessing myself. I'm with walterM. About the composting question. Also...
What is the ratio of coco to poo? And how much bizz do you give? Your plant are not that bad off, very sativa dominant looking thin leaf.

Morning Zack, those are some beautiful, trained plants. Great job.Have you been checking your ph in an out ?
Its hard to grow a plant with pretty leaves outside, in odd weather, .
Looks like you really need some perlite added.Helps a whole lot. How are you watering ?

 

[Zack]

Did not compost it got it from a nearby nursery and just layered my plants with it.

 

[Zack]

My run off PH has been pretty off by 8.0 after i started feeding the plants a specific RECHARGE which mentioned to not PH the water and just give it like that

 

[Zack]

This happened 2 weeks back and now i guess the PH is normal

Thanks mate my brother is a pro at training them..
I water my plants with bio bizz nutrients.
