Leaf Problem or too healthy?

I've never seen a plant grow so fast or have such a thick stem at 3rd week but the leaves look a little weird, is this normal?

You have deformed leaves that wouldn't be as much of a problem but it is affecting the new growth and older leaves. I think part of it was being rootbound for mine, I had similar leaves. Trim off the lower older leaves and you could transplant into potting soil if that doesn't work. If they are getting plenty of light it is something about the medium the container or the irrigation I bet.

Too healthy? What ppm/EC is the reservoir at? It looks a bit low from the looks of those watery leaves. What are you feeding with?

i think your ph is off if it were nutes they burn on the tips.. they grow like that in water if you have a crazzy swing on the ph check it ever 5 hrs.. make shure you mix your water before the roots get a hot shot of the ph swing or nutrients.. i also see rust burns that could be your nutes or your benifishals are to high??? you should spray one tea spoon baking soda on the leafs with out it drenching on your roots you might have made them volnrable to brown spots or brown mold it will dry your leave up slowly and spread to the rest of the leafs hepa filter new air in can we see the roots??

They look slightly burnt at the tips in spots and perhaps a little dehydrated looking in general the leaves look a little twisty
i do not think they are mutant types but to early to say,
they are nice and green maybe cut back on the food and wait and see what happens
they maybe just suffering from slight over feeding or maybe a little to much heat
they have the dehydrated look to me which heat and overfeeding can cause

peace

i agree with the dehydrated part it might be hot inside...

I don't know why a DWC plant could be dehydrated and if anything, it's too cold in the attic in the winter, not too hot.I have no problem keeping reservoir temp between 65 and 70. Sometimes I have to add a fish tank heater just to stay up there. I assure you it's not too hot. My tap water is at 150 ppm and my solution totals at 1350ppm. I started adding cal-mag and bring my water up to 250ppm with it since I spotted the rust spots on some of the leaves.

Oh and I keep my pH at 5.8 with pH meter and periodically double check those readings with a pH color test.

What are you growing? I've never seen a marijuana leaf look like that.

Heat directly from the lights and overfeeding dehydrates the leaves this can happen with hydro a swell as soil
if you hold the leaves with your hand the leaf surface should always feel cold as if they radiate coldness
any slight heat that can be felt would indicate they are unable to keep themselves cool in the environment

1350ppm seems a bit high for plants that young?

1350ppm, my tap water is 150ppm.

They are self pollinated hermie seeds. I selected my favorite female from the last batch and am cloning her right now.The ones in the pic are all hermie seeds though, not clones. Some leaves have 4 and 6 points so I'm starting to think the big one is a mutant...I don't care as long as she turns out to be female. Three weeks and the stem is already 1/2" thick.

I dont go past 1000 in full flower with mature plants and 110ppm tap water.

So basically they are genetic mutations. Hermie seeds are never worth growing.
