What causes this? Coco and hempy heads have a look

[Smiffy_420]

Problem: Twisted/Mutated/Odd leaf growth

Medium/grow method: 50/50 coco hydroton

Feed: and supplements used: General hydroponics, lucas formula. Currently feeding at 0.5ml micro and 1ml bloom per liter. 0.75ml cal mag per liter.

water source: Tap, ppm 160-220

Strain/age: Fastbuds Original skunk, 7 days since it broke ground

light used: bridgelux eb strips, 3500k 12 strips 100w.

Climate: Rh 45 temp 26'c

Additional info: i have 2 of these sane strain same age, only 1 is effected, only difference is 1 bad 1 is in 50/50 coco the other is 100% coco.

I know it will grow out of this, just wondering what causes it?

They will be fine. Only thin I see is your RH is a little low.

I had the same issue with some seedlings. never figured it out. Sorry I'm no help. I wanted to comment on The RH.

Although I haven't grown this yet, but the seeds are in my drawer and will be planted next month, as I see original skunk carries all the original issues of skunk
Perhaps feeding with a bloom supplement so early is the reason this happens. But I would say ignore it.

I agree. Any concern of cal lockout due to high K so early?

 

[Kinezokyprios]

As I see it is more a lack of P and too much K. I have noticed this in tomatoes, their leaves will turn like this if P is low but enough not to cause a deficiency and K is high. A grow supplement will be more balanced at this point. But you can ignore it completely if the other plant is ok because soon it will grow out of this.

Sound for the replies lad, i went with the age old method of leave 'em be and see what happens, well they grew great for 3 or 4 days, then the leaves started drooping. After lots of researching ive tried a few things and nothing seems to have made an ounce of difference.

Before making changes i was feeding 300ml of nute water (gh micro 1ml/liter, bloom 0.5ml/liter, 0.75ml/liter calmag) ph 5.8ish every 12hours, What ive tried is:

I left them dry out for 12hours incase of overwatering
I doubled the nute strength
I halved the nute strength
I moved them closer to the light
I moved them futher away from the light.

I made the changes every 12hours and there was no change in the plants condition at all, what else am i missing?

Fb original skunk, plant 1, 50/50 coco/hydroton hempy 2" reservoir

Fb original skunk plant 2, 100% coco hempy 2" hydroton reservoir

They look overwatered. Try going 24 hours between waterings for a couple days. What do you have to loose? When it gets bigger it will use more water. Young and tender. No way you can determine if anything works in 12 hours. Take a deep breath.

Yeah man i think they are, i drilled a hole in the bottom to drain the res, waited 12 hours, so 24 without watering. I watered with 200ml of nute water and had 150ml of runoff so way more than the 10-20% i read is recommended for coco. Ill wait a day or 2 and see how they go.

Ill be starting more seeds wed or thurs so hopefully ill have it dialled in by the time they are this age.
