Hi, Is the sapphire scout in the centre of the tent

 

[Substance]

The 1 that is yellowing the most is in center but in 1st row next to opening

It looks more like light burn a bit. And it usually happens to the plants directly under the light. If they are all in the same medium and you haven't gave them any extra nutes. I would just move the effected ones to the edge of the tent and wait a few more days and see if it gets worse. That's the problem with pre charged soils. It's hard to know if it's a nutrient deficiency or overload. But if the others are healthy, just wait a bit.

 

[Substance]

They are all in same medium,havent feed em yet since they seem to be ok on food and manufacturer claims there is enough food for 3 weeks .
Are u suggestin i should wait few more days before flip to flower?
Tnx for ur time and opinion helps alot i was thinkin it was light burn or soil mix might be too strong for em but its 3 weeks already so i doubt it.

 

[Paul Squiggle]

You should always fix your problems before going into flower. You don't want to start adding or changing anything when they have been flipped.
3 weeks is a bit premature for flowering but not impossible. It's just best to let them beef up a bit more before you do, but your are stuck for space so I guess you have no choice. But yeah, just wait a bit. I know you will be impatient to get the girls into flowering . We all were at first

The light does seem pretty far away though. So I'm not 100% certain

 

[Paul Squiggle]

If the medium is only good for 3 weeks, it may be deficient. But that's a lot of soil for them to eat. But you would have to wait again to see if the others displayed the same characteristics. There are loads of more experienced growers on here that will be able to help you out. They will be along soon. I'm only going off what I have experienced myself and your symptoms were my symptoms once.

yes but not severe

 

[Paul Squiggle]

Could be deficiency sayings it's on all new growth. This needs answered off a pro
I've never been deficient on new growth so I would be guessing. What type of water are you giving them?

 

[Freak Brothers]

Yeah don't flip until u sort out your problem,,in veg state they r more Hardy an r pretty robust ,,not so forgiven in flowering

 

[Freak Brothers]

U could b at end of soil nutes maybe time to add your own

Tap water that sits for 24h Phd 6.5-6.8
There might be too much minerals in the water?

Are the leafs cured up? That would be too much light? Taco-ed

Not really , I was thinking the opposite.
Just wait a few days and see how things go. Someone with more knowledge than me will be along. Plus you need to get this sorted before you put them into flower I'm at the limits of my understanding of these plants now there are way more experienced and knowledgeable people on here .
But they are not dying , so don't stress at the moment.

No problem. Have you got nutrients at hand? If so, what have you got.
