Agent's 2nd Organic Grow- Pineapple Chunk, LSD, Euforia 200wCFL/600HPS

Ok so these seedlings are 9-10 days old and i've noticed some bizarre yellowing towards the centre of some of the leaves ( not the bottom ones though) its kind of patchy like the chlorophyll hasnt properly developed. All i've added to the water is the biopac which is basically bacteria to help the roots absorb nutrients from the soil. I havent added any nutrients via waterings as afaik its to early to introduce them at this stage as the soil should hold the right amount? They are grown in biobizz soil and the pH of the water given to them reads 6.8-6.9 so im confused to why this weird yellowing is occuring anyone had experience of this or can tell me what it is. The roots are just starting to touch the drain holes in bottom so could this be it, or something else? Please help Any comments welcomed

Some seedlings can be quite picky, but my only thing that I saw that would possibly explain (since you seem to have done everything to the book) is that the medium looks very wet! Too wet a medium often has the effect of suffocating the roots. Possibly give em a few days to dry up and then give them a light watering. I wouldn't add anything at the moment. Over the next day or so keep an eye on the new leaves that are forming. Hopefully they are remaining green. How hot does the tray get they are sitting in? It looks metal of some sort.
Yellowing veins can be from various issues like Manganese for example (but with micronutrients added I would be surprised), but I think it's a bit early to start throwing stuff at em. I will check in over the weekend to see how it is going.

Good luck with it Agent!

Thanks for stopping by DST, very much appreciated, yeah i just watered before i took those pics i do let it dry out in between, im thinking you may be right with the tin, think ill transplnt em to next size pot add some fresh fertiliser and change the choice of drainage collection lol, fingers crossed

Well i've repotted em into bigger 6" pots from the 10 cm ones they were in with fresh compost, ill wait a few days and reassess.

Ok so put em in bigger pots, The first pic ( Euforia) is still a bit slow of the mark but a healthy green, then the LSD which is also quite healthy, then come the faster growing Pineapple Chunk, both with a patchy yellowing between the veins, one noticibly more than the other as you can see. I'll have to see how this progresses as dont want to do anything rash atm. I did put my problem in the newbie part of the forum for advice but wasnt convinced enough to act on some suggestions... Yet. So many factors may be to blame - the strain, the rate that strain grows, the fact the roots had got to the bottom of the 10cm pot within 9 days, the metal tray i temporarily had them in, or even the fact that the Pineapple chunk was closest to the firing line of the chill off the inlet fan- who knows but heres the pics. Comments welcomed

Ok so when i started i tried to germ 2 x LSD, 2 x PC, 1 x Euforia and a left over seed from Nirvanas WW ( which i've had stored for about 5 years total now lol and used for my last grow too) When the WW and other LSD failed to sprout after 4 days i chucked em into the garden amongst the bedding plants slightly miffed they hadnt sprouted Anyway just passing this afternoon , guess what i find lol 2 tiny seedlings YAY! so i guess failed seeds are worth hanging on to for another week hehe! They are massively behind the others by about 10 days. I think the taller more developed one is the WW and the smaller one the remaining LSD so after all it was a 100% germ rate in the end lol! will have to keep an eye on the WW especially as its not from a feminized batch like the others, if it turns out male ah well, but i do fancy trying my hand at genetic crossing if anyone could give advice nearer the time if it turns out male But, YAY now i got 6 plants instead of 4 even if it might cock up my flowering times lol.

P.s unless i've clumsily repotted wrongly, i got it wrong about the yellowing seedling, it is in fact the LSD and not the pineapple chunk as i first thought so hmm.

So plants are now just over 2 weeks old.( apart from the slow ass seedlings that didnt germ at the time they should have).

Lowered the pH of the water to 6.2-6.4 using cider apple vinegar and started to add half strength nutes, they are starting to bush out a bit now and seem to be liking the nutes, even the poorly plant seems to have all green new growth ( pic 3). Perhaps its just a hungry "feed me seymour" plant i dunno lol , but glad its finally coming green . So you guys thnk they look ok for this stage?

Comments welcome
