Help! ETC is happening?

[David Ferguson]

This is my first time doing Autoflower plants. I started them in a clone tray and they seemed to grow slow at first but started growing more successfully in the second week. Very green.
Transplanted them into a Dutch bucket system in my grow room and all of the leaves starting at the bottom and making their way to the top seem to be dying and turning white. Please help me to understand if there is a problem that I need to tackle with this and or what I should do. I have attached pictures of the two worst plants. Thank you and please respond soon

How high is your ec? I know a lot of times it's not wise to transplant autos too. But I wouldn't see it sound that.

I'm not sure what you mean by " I wouldn't see it sound that"....but as far as nutes, simply- PH approx 5.8...using Skunkwerks RX all in one.
Also fair to mention it's a HYDRO grow

F-ing auto correct... I get lazy on proof reading sometimes...The word should have been "being" instead on sound. I think I would check ppm's. Autos can be sensitive to nutes when they're young.

Just looks like the rockwool plug is too wet, judging by the algae on it. They'll probably be fine once roots grow beyond the plug. Basically the roots are suffocating. The top looks healthy so maybe they're beyond that point already, just the early leaves were affected.

Thank you (both). My watering schedule WAS too frequent before so I do agree on maybe overwateting....and great to know because I was struggling with the algae problem anyways. Watered only 1 time daily for 15 minutes now and that may even get reduced. I agree tops look good, but they just need to shoot up a bit before flowering, so that's a concern. It's week #3 today so yeah.
Beyond that, I am hoping for success from this point on. I am transitioning into a soil only grow from now on, since it's more forgiving and seems people like organic soil grows too when it comes to their flowers. Might keep 1 hydro resevoir, but probably all soil (what do you all think??). Thanks again!

Just be careful about commercial soils. Often contain pests. Not many brands are actually sterilized. Could sterilize it yourself though, just have to read up on it, usually involves an oven. Might be other ways, I don't know, I never use soil. Maybe just use a soilless mix and organic nutes. It's just "drain to waste" hydro but with organic nutes. Hydro in a soilless medium works very well for me. I never tried the organic nutes though, so can't comment on that. Soil itself is really not a good grow medium. Take a look at the grow videos on the Greenhouse Seeds YouTube channel. They grow each strain in both soil and soilless hydro, at least it looks like soilless, could be DWC. They talk about flushing them so I guess it must be a medium. The soil ones are always pathetic looking compared to the hydro. After watching those vids, you'll wonder why anyone ever grows in soil.
