Why is it so wavy?

How often are you? Watering to me it looks like you're just slightly overwatered otherwise they look fine over watering will do a few things. It will stunt their growth and also make the roots slowly but surely rot try to water every 3 days. See what it does. Think you'll be just fine

Some plants just start out like that.........it is completely ok and nothing to worry about. It is not caused by anything, it just happens to the first few sets of leaves for no real reason. Plant will grow out of it eventually, however, some plants will grow their entire lives like that ..........it can be a genetic thing in some cases. It will not affect flower growth, yields or potency in any way. Always water the entire pot, not just next to the stem, roots will not grow into dry soil, ...... this may be part of the reason why growth may seem slow, although a 95w light isn't really going to set the world on fire!

Maybe ph wrong or ph goes high and low with every watering (ph swing). I have often this problem, but when i checked exactly the ph, it disappeared. Calibrate your ph-meter. Good luck!

I'd say it's a sign that she would prefer a slightly more humid environment 😽

You can have been feeding it to much or watered it to much that slows the growth in the beginning. And the light can be to close as well. Easiest mistake in the beginning is over watering. so let it dry out some before feeding again, higher the light a bit don’t worry because she looks super healthy besides slow growth 😃 Good luck my friend 🤩

maybe a bit to much water??? I don't think its anything to worry about plant looks healthy. The bit of yellowing in the center on new growth can be normal. It should green up in a day. If not it might be an issues with S. Should update your diary on what you are feeding them. 450ppm of what.
