Dark green color - Leaves curl down no necrosis

Hey!

Please help me - i got no clue whats going wrong..

I got 2 blueberries from DP (indica dominant) in day 38 of flower (9 week strain). It's in soil (quality potting mix, the rest 12 girls like it) pH around 5.5-6.5. Pot size is about 3 and 5 gal.
They are sitting under 2x400w HPS. Temp is about 82-86, RH is 40-60.
I give them water every 3-5 days, using canna terra line according to their schedule - 1600EC in start of flower then 1900EC(current) and 1400 before flush.
After i started adding PK 13/14, a few branches recovered but most still look bad.
I don't see signs of nute burn yet, leaf tips seem to be green.

I guess this must be strain specific - i have 3 other strains (14 plants total) in the same room and they look really healthy.

This is an older pic to show color without the HID:


This is made under HID, but shows how weird leaves look..


Any info is appreciated!
 
Dark green leafs curling down like rams horns ah !

Nitrogen toxicity e.g to much nitrogen, might be over feeding ! or nutrient sensitive strain ?

Thanks FuzzyDuck!

I'm not sure since fan leaves show a bit N def and there is no sign of nute burn yet.
Anyway i will still try to flush them with clear RO water.
Pity i fed them a day ago . Should i wait until they need water again, or just do it anyway?

The strain is certainly sensitive.
 
Pot size is 3-5 gallons? ...you wanna keep them going?..flush baby, flush 4 gallons (if pot size is 4 gal) of fresh clear water per plant, repeat in 3 days if no change, flushing won't hurt your plants, will make them hungry for a day or too, but should recover well in a couple of weeks.
You are killing your plants with kindness..lol

Thanks - this seems to be the case. Never thought this can occur without burn.
Leaves gettin back to a lighter green color on more and more branches. Will repeat flush 2 more times, with 20-30% base nutes and half dosage PK (she shows signs of P def i believe).

Yeah leaves started drooping, few days later the lower leaves started going dark green and a some orange brownish spots appeared, just repotted them into bigger pots with bio bizz all mix, they were just in light mix before so hopefully that ll help?
