Normal growth???

ok so i planted this on the 9th just after germination... so what 13 days... There are a few yellow spots so i replanted and made my own medium... i used spahgum peet moss, perlite, a little organic miracle grow and a little lime... i have 2 125w 5000k and 1 75w 6500k cfl bulbs on a 18/6 cycle... ph in water is optimum as for soil i am still waiting for my tester to arrive... let me know what u think, i am new to this... my box is 2 feet tall by 16 in wide and 16 in deep... oh also i think i might need to flush the medium?! on another one of my smaller "plants" there are yellow tips... when you flush im kind of not sure do you leave the plant in the pot/medium and run the water threw or am i just stupid? i appreciate all criticism! thanks... strain is feminized delicious carmelo if that helps?!?

oh temperature varies from 72-90 degrees f and humidity about 36-45%... is 90 degrees to hot?

your plant is a little behind but all is well. id say get fox farm ocean forest soil it is great out of the bag but i prefer 25% added perlite. and 90 degrees is hot for indoors. you want to range 70-80 indoors 85 at very most which is still bad for growth. ideal 75 is best for growth hope this helped.

As you can tell from my posts, I am also new, but from what i've read I believe to flush you take 2-3 gallons of whatever water your using on your plants per gallon of soil to flush. My pot I use doesn't have holes in the bottom so I tend to be very careful when watering or adding nutes, because if I overwater, or put to many nutes it stays like that until its able to use it all up. Also just a note, all of my plants that i've started including the one I got now, had yellow tips because I use a premade soil with nutes, but give it time, let the plant grow and eventually it will be able to absorb all those nutes and be fine, its just too much for a seedling, imo. But as long as the yellowing is just on the tips and no worse than in the pics YOUR baby seems FINE because those leave with probably not grow any bigger than that anyway lol and will be old news in a couple weeks!

so on flushing i get the ratio but you leave the plant in the pot as u flush all of that water through?!?! wouldnt that possibly kill the plant do to over watering?? thanks

ya 90f is too hot try to keep it below 85, 70-80 is optimal

well here is the one i was talking about with yellow tips yeahman... its an auto-berry ryder strain... i nicknamed it stumpy because she is so compact idk what her problem is... its probably the growers problem why she is that way... i just cant figure it out.....

Dude if you flush with that much water I think you'll drowned it. Your plant does'nt look bad just needs more light to grow fast. That other guy, get a pot with holes in it and easy on the water.

all of my pots have holes for drainage... well then is there another alternative to bringing the soil down without flushing?? yeah it may not look bad but that plant has been planted for about 15 days now... kind of behind the curve...
