Pecliar shaped leaves.

Hi guys,my turn to ask the pro's.

Apart from having minor N deficiencies,i can't explain why these leaves are pointing upwards and are not fanning out as they should.

Here it is, WW at 21 days.

Could anybody explain?

My guess would be heat stress

heat or nutrient stress, leaf tips are affected

Sometimes new growth looks like that because it can't fully lay flat yet as it's still growing, not sure if that's the case since the picture is so blurry. Ph/nute issues could be too blame since i see some discoloration. Wouldn't worry about it too much unless it stays like that.

Whats your pH?
What medium do you use?
What are you feeding and at how much?

Need a little more info please............

 

[hamstorg]

Soil pH used has 6.5 6.7.
At the moment i have no ideea how much the pH of the soil,since i dont have a pH meter at my disposal.

Its true i had some heat issues,around 32-34 for a period,but now i handled it and its stays at 28-30 max.

I has been fed 2 times,mixed Vitaflora NPK 8,5-3-4 with microelements,mixed 3 ml with 1L of water.

It says the recommended dosage is 5-8 ML for 3L of water.


Any ideeas?

If your lucky the leaf will close up on any Mites and white flys and eat them like a Venus fly Trap lol

Here's an update

At 23 days.

I also feel that the plant is somehow growth stunted,i could definately be bigger at 23 days under a 250W HPS?Right?

And the leaves where the stress is noticeable or the deficieny,are very very dry,they break even on the slightest pinch.

Ok, first veg under a Metal Halide not an HPS, they'd grow better. The "taco tounge syndrom" is probably a nute lock out. I had the same problem with a Bubba that was fed to early and had to be flushed twice and then recovered great.
The leaves feel so dr because when they curl like that they're trying to get rid of water but cant, they're pores are clogged, flush.
