Seedlings keep stalling

Been growing over the past 6 years and have never had this happen to me before i start me seeds they pot and sprout then stall out and stay about an inch tall. Using coco and petite
4x2 tent
900 watt mehinzi led
Temps are 75-80
Ph 6.3-6.5
Seedlings are 14 plus days old and only anf onch tall and one set of leaves

This happens

Your coco looks dry!??

PH seems a bit high for coco.

Drop to 5.5 maybe ?

Swing between 5.8-6.3.

how close is your light? is that 900w actual draw? LEDs are very focused even though it doesn't generate a lot of heat it's still very powerful and seedlings don't need a lot of light. Mine didn't really start growing until I maxed out the distance to about 52 inches, it's a "1200w" 250 actual watts, the manual suggests 4.5 - 6foot distance. maybe raise the lights or put a shade cloth.

It was the ph. I dropped it to 5.5. Plants started to take off but i stalled then for almost 2 weeks not sure if its even worth finishing them now

you ph'd your coco ? i dunno if you do, i never grown in coco.

like soil you need to test the water coming outta the bottom to get the right ph balance.

ph your water, water right though so it comes out the bottom ... then ph test that water

Yeah i did all that they are growing now. But not sure if its worth finishing then because they stalled for 2 weeks

900 watts a lot for a seedling .. am i wrong ? led's

those images don't look like you've water all the way through.

well if they're growing leave them .. they should keep growing if they happy

just been stunted a few weeks thats all

use 23W spiral cfl for seedlings.

Ph is fine now. Ans plants are green and growing just not sure if its worth finishing them

Thanks man ill finish them and see what happens

Put them into solo cups when they first go into dirt. You are wasting weeks waiting for the plant to grow roots out to the inside of the pot. Plants need to support themselves by building a rootball. By using huge pots right off the bat the plant will spend a lot of extra time growing more roots than necessary.

Good luck, BigSteve.

These aee autos so i was advised against transplanting. Maybe starting in rockwool cube rather then right into the medium ?
