Bottom growth turning yellow early in veg. new growth is healthy green

A week ago I wanted to see if the roots were reaching into the growstones so i pulled out the cube to see and they were about a quarter to a half inch reaching down and they were all white, this was a tiny root on the side, but you may be right. The first 3 weeks of their life they were quite wet. Think it'd be worth it to cut into the RW with a razor to see if inside is brown?

I'll pick some up tomorrow if they stock it at my hydro. *EDIT* checked online and they have it 36.99 for 1L. Expensive. But thats not a problem if it'll do some good, i'll take your word for it and try it.

Thanks

Not sure it was the RW. I'm starting 4 chronic haze's the right way. No nutes, soaking RW in 5.0 ph water. Just spun them out in the salad spinner and tested the run off left in the spinner and it was 6.2 so I chucked that water and put more 5.0 water in. Tomorrow morning i'm going to do the same and test the run off. Spin them cubes down to about 25g each and plant and put on heatpad and put in a humidome.

Hopefully these work out. I'm getting discouraged quick.

But i'm going to follow masp's advice and use some superthrive. Hope they make it. They're still putting out green growth.

sounds like yr doin the right thing w the chronic haze. superthrive is worth a shot. dnt get discouraged bro. it will all come together in time

Yeah I soaked the RW in 1ml superthrive per gal of water. Hopefully they come out alright this time around im going to use my 4ft 6 tube t5's on them instead of my 600w MH on seedlings. Conditions in the room seem good as far as temp and RH. I just think I got aggressive with the nutes too early and stunted the power africas growth. I also over watered in the first 2 weeks and probably left them in the dome too long. Then once I saw roots out the bottom I put them in the stones and side fed for the first 4 days, like I watered around the RW in the stones but didnt get the RW wet, except whatever wicked to it from the stones. Then I flooded every 2 hours. Now i'm doing every 6 hours.

See what happens, I hope the slow growth right now is from them setting into the stones and not from root rot. But its been 2 weeks and there vertical height hasn't increased that much. So i'm assuming something is messing with them. I could throw them out like you said, but it's practice I figured.

The power africas are looking better. They're gaining some vertical growth. I read recently that once a plant is in flower that it takes a long time for it to veg again. I'm wonderinf if that day my lights went off and it had 11 hours of lights on made them go into flower and this slow growth I'm seeing is them trying to go back to veg?

The likely scenario is probably transplant shock as the one plant that I lifted the RW up from the growstones to check if the bottom was getting wet looks the worse. Its leaves are really narrow and not as much growth as the others. I think I reshocked it when I lifted it up.

I'm noticing a husk type texture appearing on the stalk...its like grey and flakey. A piece even flaked off. This normal? They're getting wider...the stalks.

So I took masps advice and flushed the plants with a liter of 5.8ph water and superthrive all over the top of the stones and rw in hopes of flushing excess salts out. Then kept the pot covers off so the rw would dry up. Repeated this process once the rw dried back out.

The 4 chronic hazes I thought I did by the book I was reading that I messed up again. Forgot to drain the 5.0 soak water from the rw fully...instead I drained the cubes to 20g(4 times their weight). But they all sprouted and look ok. So maybe it wasn't that big of a deal

OK,

I'm not the most experienced grower by any means, but I am really good at cloning and vegging.
So here is my 2 pence.

In my experience, it has been impossible for me to tell how wet the tiny rockwool cubes are without picking them up. I now grow sog in 4' cubes and I still have to pick them up occasionally to see how wet they are.
So once you plant the cube in the hydroton it becomes very difficult to determine the moisture content of the cube. Also, if the cube is a little to low or high in the pot in your DWC the rockwool will be to dry or more likely to wet. (Ask me how I know)

It looks to me like and from what you are describing, the little plants never had a chance to root properly and some section of root died thus starving the plant. the moisture gradient between the rockwool and the hydroton was to great for to long a period of time.
Now people have said to top feed for the first few weeks, but that doesn't address the issue of being able to read the rockwools moisture content.

What I did to resolve this in my situation, was to go to rapid rooter, sure to grow, or equivalent. cubes. They change color as they dry out. I have gotten to the point that I can tell by color when they will need to be watered again.
Also I use Dyna-Grow and start feeding at about .4 or .5 EC as soon as the clones leaves perk up which for me is about 5 days in the cloning dome. Google "cloning with jjscorpio"
With seedlings, I start feeding as soon as the first real set of leaves come in.

Here is my cloning area and picture of 4 plants.
The 2 in the waterfarm are Sweet Tooth # 4 and the 2 in the center are Moscas Azucar and Alein Dawg F2.

The Sweet Tooth are 11 days from germination and the other 2 are 22 days in. Also I took clones from the center 2 about 3 days ago, so they are about 4" shorter than they would have been, Gotta make mommies you know.

Well I hope this helps, and if not I got to pimp some pics anyway.
