I have 5 Holy Grail seedlings that popped and sprouted out of 6. The last one never even popped. I have two that are a month old (are doing great and are now in 1 gallon pots) and 3 that are 2.5weeks old and struggling....if you can help I would appreciate it!

They have been getting water....but I accidentally watered them with the early veg nutes I am using on my rooted coco clones yesterday. They have been looking lighter between the veins with dark green veins for about 4 days...my man is freaking out and wants it fixed asap. A couple older seedlings were doing the same sort of lightening leaves with dark veins as well but those seem to be improving on their own and new growth is fine. Any advice would be amazing!

I'm guessing your soil base mixture should be taking in around a ph of 7? & your coco solution you poured in was ph'd to 5.8-6? Just flush em with some fresh ph'd water, observe for a while & reintroduce your feeding at 1/4 to 1/2 strength.

But, wait for more advice also, that's my guess, not your solution!

First thing I'll recommend is for you to transplant them ASAP.

Go lightly on the feeding. You don't want to fry them.

Over time just slowly increase the feedings.

They are in Tupur coco right now. It has kind of a lot of perilite in it (comes pre mixed). I will transplant them today. My other rooted clones and seedlings seem to be doing well but these 3.....not so much. THANK YOU for the fast responses! Any additional info/ advice is welcome. This is my first time working with seedlings!

1. Ignore all other advice. (Other than Soundy and Troutman.)
2. They have poorly developed root systems, which is why they're tall and thin.
3. If they're in soil that has nutrients in them, give them 0.2 EC (0.4 max) of high P/K nutrient solution (Plagron Green Sensation, Atami B'Cuzz flower hardener), then let the soil dry out. This will put a good root system (P) on them and build a strong stem (K). Repeat until they have a large root system, and have a slight nitrogen deficiency. Then proceed to nutrients that are high in Nitrogen and Potassium (which helps in Nitrogen absorption).
4. In coco, mix 0.2 EC of your coco nutrients, and 0.2 EC high P/K flower hardener. When they're larger use 0.4EC of coco nutrients and 0.2 EC of high P/K nutrients.

Putting extra roots on these plants will be great.

Thank you @Tanzanianmagic. I will worm on this. I always felt like a good plant starts with good roots. Works for my tomatoes....makes sense it would work for this too! I appreciate you guys for helping me!

Btw...great news...after I transplanted these 3 yesterday the smallest is already perkier and the other two look pretty much the same but given the improvement on the lil one - I'm hoping for good things!

Glad they liked the transplant. If your grow medium stays wet and soggy for long the plants roots cant grow or breathe (drowning!).

excellent advice thank you for writing that

[GrnEyes]

Thanks guys! The seedlings are all doing better...magnesium deficiency seems to be clearing up as the leaves are the normal beautiful green that they should be.
