AK48 leaves light green and curled pls help :)

[demsone]

Hi All,

So i am growing an AK48 autoflower and i am a bit confused or concerned because the whole plant looks twiggy and it's rather tall compared to my other grows i have going. I will post some pics below so you could see for yourself. The colour of the leaves are all bright green and the fan leaves have gone yellow. There is a lot of curl downwards and upwards. Lot of dropping going on as well. The buds themselves don't seem like they are filling out. I don't know if it's a N deficiency, if i am am over feeding them or if it's an issue with my HPS light.

I am feeding her every 3 days and i use the weight and top soil dry test. All times she feels light before a feed.

Grow Area: Grow tent 0.9mx0.5mx1.6m. I have the HPS 12 inches from the top of my other 4 plants which are around 6inches high. i am growing with the AK48 at 65cm in the far corner of the tent so its not close.

This is what i entered into my journal from my feed today:

Days from seed: 48 (week 7)
Days flowering: 15 (week 3)

Tent temp: with fan 19 deg C without fan 28 deg C

Height: 65 cm
Water: 2 litre cweed concentrate + 10ml proganics bloom + 15ml monsta bud
ppm: 1665
ph: 6.1

This is what i recorded with the run off
ppm run off 1890
ph run off 6.8

Any help will be appreciated!

are you not suppose to use grow with the bloom?
they also look over/underwatered
that not 2l seaweed
28c is to high
and your overfeeding as your ppm in runoff has gone up not down

I agree with agito,to many nutes to often.Could be over watering,roots lack oxygen.

They also look over watered to me. Also appears to be a pH issue. Going in at 6.1 and getting run off at 6.8 indicates that the pH is high. Run off should be in the 6.3 - 6.5 range.

Thanks for the replies guys.

Yeah overfeeding seems to be the problem. I just flushed her out with 4 litres of water with a ppm buffer of 140-150ppm and a ph of 6.3. The run off was 840/700 ppm and the ph was high at 6.9.

Was that a wise thing to do? I wont water her for another couple of days and see what happens. Will hold off feeding for another week and get the ph down.
