one of my seedling is 5 days old i noticed the tips of the cotyledons leaved are getting yellow also my 3 day old seedling looks like its about to do the same thing,by 5 days old i refer to when they poped up from the soil,I have "2" 1000 watt lights 50 inches over them in 3/4 liter pots with 30 perlite and 70 Coco coir ,room temp stay between 74- 81 F all day,night temps are 68 - 70 F, , Ive been watering them with Advance Nutrients Sensi Coco grow 1 ML per L , with water thats 230 ppm and 5.8 Ph, I watered every time i see the top of the coco startin to dry out.. I wasnt gunna water wit nut. until they were atleast 4 inches tall but i was afraid of shocking them , i just flushed all my Pots with 50 ppm purified water and 6.1 Ph ill see how my babys react after a day , o havnt added Co2 yet , ill have it in 2 weeks , My room size is 8 x 8 its my first grow :D Thank you guys ( i know its kinda hard to see the yellowish in the pitures but its way more noticible in person)

So you have 2000 watts hps dousing your seedlings with more light than they can handle? scale back the lights for right now lol. Pop one or two cfls above them until they gain some size. The yellowing is probably from heat stress, as you are giving them the same light you would 10 flowering plants lol

Sure thing man. I'm pretty sure you'll be fine with the 400w, and don't worry about cfls. Your plants do look fine though. A lot of my seedlings have been that same color and were fine. Give that 400w a few days and I bet you will have some healthy plants.

I would say they look fine, I'm growing in coco as well (still a beginner tho). I'm learning that you have to be patient. so I'd say just wait to start feeding nutes until you get the 1st pair of leaves (not cotyledons)
Maybe you could take a look at mine an see, I'll make sure I keep an eye maybe I'll Learn somethin from you. . GOOD LUCK!
