ok dude you think differnt i think differnt.so you i respect your opinion .

i asked whats the problem in pic? thats it

thanks anyway

what I can see going on.

Leaf tips turning white- Is a sign of a Magnesium deficiency.
leaf margins (edges) curling up. - is also another sign of a Magnesium deficiency
deformed leaf growth. (center, above your bud + other leafs) could be a sign of a Phosphorus deficiency.

IMO- your bud size for 25 days in doesn't look to bad.
Potassium deficiency can be associated with slowed flowering diminished yield.

Fungus Gnats- be careful, your growing in CoCo.
There is no food in the CoCo for the Fungus Gnat Maggots to eat.
The Maggots will feed off your plants roots system.
This can cause a lot of problems for your plant.

Here is a good link at RUI for CoCo

Good Luck on Your Grow.

Do a little research on the strain your growing.
The strain you have might want to be feed more food.
