leaf curl/claw on new top growth

specs:
bagseed
400w MH/HPS
4x4x7 tent
GH Flora Nova Grow/Bloom..cal/mag..RO water,and some Bud Candy
top soil with sand and perlite

feeding schedule is 1/2 tsp of bloom nutes to 1 gallon of water..then 3 waterings of just RO water..then another feeding.

today is the start of week 3 of flowering..of the 2 plants all of the top new growth on one plant has the claw effect going on.

the other plant is doing just fine..any ideas of what could be the problem?




heres a pic of the plant doing just fine.

Is the clawing plant closer to the light or in a spot warmer than the other plant?

nahh the light is about 4 feet away from the plants,and the plant that is doing just fine is just a bit closer to the light.

stop all water/ferts. get a some air movin' on it. re-evaluate in 72 hours

well the temp in the tent is at 66F i have a carbon filter in there and a fan..also all the windows are open as its always been.

the fan is set up to draw cool air in and blow out the warm air.

a fan blowing on plant!
lol

nahh its aimed just above the top canopy,and just below the light.

are u not supposed to have a fan moving the canopy?

i believe that plant is severely over-watered. aim a fan at it to add in transpiration.

here's an idea of my setup.

yea it could very well be that it is over watered..that plant bucket always seemed heavier than the other when i water.

could be that its just not drinking as much as the other plant.

so here's what i did i turned the fan to low and aimed it at the plant and closed up the tent to get it a lil warmer in there.

Overwatered or too much nitrogen.

Add sugar to next water...if the next day ( yes it works that fast ) the leaves look straighter ( not clawed ) it's nitrogen.

Add 2 tbps per gallon.

how about Molasses?

No...has to be sugar.

Sugar binds with nitrogen the easiest...molasses binds with everything ( Which could cause nute def....which is why molasses is usually used at end of harvest for flushing and last minute bud plumping )

And yes I know molasses is just the left over from refined sugar production.

Ive got a little dark green and clawing going on too. Think I used too much flower tone. Can organic nutes be flushed? Its probably too late anyway because I just cut off the bottom of the container and buried it in the ground. lol. Thanks
