Same conditions different looks, slow growth

[Odissey]

Hi everyone,

I have just started two seeds from Fastbuds, Tangie and Purple Lemonade.

I am growing in a micro tent and a 55 w cob cree LEad which performed fantastic last round ( Fast buds GSC 88 grams dry in a 40x40x80 cm space).

The media is a special coco from Bcuzz which has very coarse coco parts. The Purple Lemonade germinated 7 days ago and the Tangie 6 days ago. They started well but havent grown much at all since. The Purple has curled leaves so I thought I was overwatering, but the thing is that this coco medium dries up super fast (like in one day). The Tangie on the other hand has leaves pointing straight up but is also growing super slowly. I do not know whats going on. As for ferts, I have been using AN Vodoo juice and 0.5 ml/L ph perfect AN coco A&B.

Can you please help me figure out what is going on? Is this medium not suitable for seedlinga maybe? Should I start over or give opportunity?

Plants look fine to me. Different plants do different things. At this stage is very slow, in a week or two they will really move. Right now it's about the roots building up. Make sure you don't water too much, just a little each day.

Thanks for the reply! I see. I was only worried because I had never seen this extreme curling of leaves and I do not quite know how to water since it is drying so fast and I am afraid the roots will be harmed by it.

Actually I do not think they are ok. Now the Purple has some spots on the leaves and is curling even more. What do you think this is?

This is what the medium is like top to bottom? This very rough looking coco, I have serious doubts about it's suitability for cannabis... coco needs to be aged, broken down some which the original production facility should do... Coco is initially loaded with Na and K; after it's ready, it needs to be buffered (not pH) for it's peculiar CEC properties (cation exchange capacity), namely for Ca and Mg...
Any coco grow needs to run differently than true soil; treat it like soil, and things will go sideways soon enough... This stuff looks wrong on several levels... there's no need or advantage to such a course mix, coco is already very porous, springy and drains and breathes readily which is why it's considered an hydro medium mainly,... done right, monsters in small pots can be grown, but it's a steep learning curve and a lot of labor when done by hand!
I see no info about pH or TDS/EC going in, or coming out...typically, 15-20+% run-off each time, feeding often at lower ppm's-- like hydro in many ways... if you've not done some research on coco, best do so soon... there's some good info in the coco section here....
IMO, you should change out of this ASAP, I have never seen a single successful grow in this chunky stuff to be honest.... problem now is, transplant shock and stunting... Or you can read up on coco and try regardless, your call...

Hi Waira! Hows it going? Well last grow I used this coco and I have never seen faster growth rates, which I hypothesize is from the extra oxygen. I had a plant in a 1gal smart pot thay yielded 88 dry grams of top quality bud in a space 40x40x80 cm with a 50 w LED!! She nearly did not fit in the tent. I believe the problem is that this is too coarse for seedlings to take root. As for ph I am using 1ml/L AN ph perfect and Vodoo Juice so I am not measuring ph. I have already popped two new seeds because I think these will not make it unfortunately.
