Mandala Hashberry question

[flybynyt]

I am growing 10 hashberry plants from seed and I have three plants with these very large but strange looking leaves. I have never seen these type before. Has anybody seen this type of pheno before?
I am growing in a soiless mix in 5 gallon grow bags, under a 600 watt HPS, with co2 injection. they are about 6 weeks from seed. I am using only Super Tea organic guano and Dr. Earths micro nutrient folier spray. Besides that the plants look really healthy. Thanks.
Two picture are in my gallery. leaf1 and leaf 2.

What are temp and RH in your closet ? Looks like you got a heat or humidity stress.

RE: Hashberry

RE: Hashberry

Heat temp is 77 degrees F., and the RH is 43%. Sorry I should have included that. the weird thing is, besides these few leaves the rest of the plants look great.

Are they close to a fan ? This could cause this kind of issues.

 

[flybynyt]

Yes. Actually there are 3 fans. A Lot of air flow. I wasn't aware this could be a problem. Should I reduce the air flow?

The fan usually dry the air next to it, so leaves in front of it are lacking humidity (it explains why the leaves are curling : they're trying to keep all the humidity they can, as you'd do to warm yourself if you were too cold i.e.) .
No big deal. You can move your plants everyday to avoid that, or just move the fans so they're not blowing directly onto the plants.

Sometimes when the fan blows directly on the leaf too much wind makes it so the leaf cant breath, how ofter do you water? make sure the pots dry out between each waterring. some of my leaf on the mandala strains were doing this to.

Thanks guy's. I will move around my fans so they are not directly blowing on the plants. I have been watering once a week. I have them in 5 gallon grow bags, but they seem to uptake water quickly. Great looking plants I must say. I am surprised how long they are taking to show sex. I have already determined that 3 of ten are girls, but the other 7, I just can't tell yet.

Mandala Hashberry and White satin do tend to have leaf mutations. Sometimes you get a pistil (hairs) on the fan leaves. Mine are all twisted looking

That looks like heat and poor ventilation seems maybe you need more fresh air. also maybe more air movement with your fan blowing on them. Some of the other pix in your gallery show classic heat cuping on the leafs. As for the fans blowing on them to hard my fan is a wall mount and blows on my plants pretty hard and I've never had this problem.

Did you guy's inexperience it taking a long time to show sex? I had 3 show female sex one after another 4 weeks of veg, but the remaining seven are undetectable yet.
