hi guyz, sorry i got really stuck and couldnt post the updates.. but i am afraid there is not much good news.
the +Speed died the same day when i got home and the smaller Devil Cream also was in same condition. i think
@XxxAuto you are right about light issue. they had been kept under low light for too long. so i gave up on both plants and threw them away. they were dry and finished

i checked the soil but it was dry on top and very lightly damp near the bottom. no way it was wet.
@Fuggzy . thanks bro for keeping an eye here. i was planning on using the same soil for bigger pot but after seeing your post (if we reach that stage! lol), i have decided to add a mix of coco, perlit and vermiculite to this soil mix. i got it today and made pots for two new seeds

. i roughly added 30-40% of coco, perlite, vermiculite to current soil mix and planted 2 new seeds in them. i hope that turns out better
for the light, i got today to work on it. the two barely surviving plants are out for some sunlight. so far have managed to assemble 1 COB. lets see how it works. i am running it on a 36V 3Amp constant current driver. the specifications say the chip brand is Epileds, its Color ratio is full spectrum, 380nm-840nm, and of-course.. its made in China

lol.
and now the pictures..
+Speed.. that died
+Speed.. barely surviving and showing exactly same symptoms as other plant. i hope sun and new lights help bring some good luck!
Devil Cream.. same story as surviving +Speed
