I am not experienced enough to comfortably diagnose.
I will say the color looks fairly dark.
If I was to guess I'm pic am in I would say possible N toxicity.
But...rereading first page, you are using biomix light/perlite and don't plan on nutes until flower.
Hmm. Not a clue bud.
Looks to be no big issue, regardless. Something ti keep an eye out.

I'll take some more photos shortly, lights have been off for maybe half hour, and you can judge true colour and discolouration then. Watch this space!

what are you watering with? tapwater? is the veins in the leaf yellow? or is it the light?
In my opinion it looks like a mag deficiency but could be cal or iron too.
Edit: On second thoughts the more i look at it the more i think its a potassium def

Yep, just watered sparingly with tap water that's been stood in the tent for 48+ hours, to dechlorinate and bring up to temperature. I'll go have another look in a mo, busy with the baby right now!

Yeah, it does look a little potassium deficiency, doesn't it? Is it too early for nutes? I've got veg/bloom/pk but I've been holding off, she's so young!! Might post in the plant problem page, see what responses I get....

I start nutes on day 10. .5ml/l GMB. 2ml/l voodoo, b52, calmag.
I use Promix bx, which I believe is similar to your biobizz light.

Sick, I have tried to figure out what is going on with your little one.
I'm afraid I am just not making a connection.

In my modest opinion however, I would recommend a light nute feed, 1/4 strength.

I am watching your thread in the infirmary. I am sure you will have it all sorted out soon.

Peace

You reckon? I was a bit worried about feeding her, in case of a nitrogen overload. What do you reckon?

The nutes I have are Hydro Coco Grow, 10-5-4, recommended dosage 2ml per litre, the pots are 15 litre.

I also have a 50ml sample of Plant Vitality Root Zone Mass, but it doesn't state nutrient ratios on it. Its designed for early development, but probably too hot for sensitive autos.

I am not familiar with those nutrients. I'm fact, I'm not entirely confident giving advise here.
However, the recent pic you put up looked to be dry. If it feels as dry as it looks you will be watering regardless.

The reason I would give 1/4 strength recommended nutes is because with your medium having no nutes, I just can't imagine it can possibly being a toxicity.

Sorry for the late reply. Got caught up

Please don't make any final decision based on my opinion. I am not experienced enough to take that responsibility.

Hahaha, that's fine man. Yeah, she was rather dry, deliberately. Been really trying to make those roots work, and was waiting to see whether consensus said to give straight water or a feed tonight. I went with water right now, and will see how she progresses in a day or two.

I also topped with a layer or perlite, mainly because it looks pretty! Photo updates tomorrow, hate taking light on photos!!

Cheers mate, thanks a lot

Forgot to mention, also raised the light a bit to hopefully force a bit of stretch, and will be purchasing some kit for low stress training tomorrow.

Considering switching lights to 20/4, as temperature sure does drop quite a bit during lights off, so looking to reduce that cool time some.

Does the soil you are using contain nutrients?
i would hold off of nutrients just to be on the safe side,
there are products you can add for phos,cal deficiencies etc, Cal Mag comes to mind but at the moment i can't think of the other ones lol

Whats the soil? How old? I read the current page but not the other 2. How many times a week water? Looks like some sort of p deficiency to me. But being an auto, it should not have any deficiencys and if so, you should def be helping her along to recover ASAP. Any stunting will drastically hurt your yield. I'd hit with a 1/4 strength of some sort of VEG nute and be sure to water it a few times inbetween the next feed.
