First grow,can gh ph down be used in coco choir grow?

Ya bro

Thanks bro. i have seedlings 12 days old today. I germinated using easy plugs, put them in propagator after 3 days the tap root was down, so i mixed up coco and potted it. And put it back in to propagator at day 8 it was well sprouted 2 to 3 inchs so i gave it the first feed. Being careful not to over water, when i popped into grow shop he gave me general hydroponics ph down, after first feed it been 4 days.. it just topling over i have ut supported with a tooth pick. On first set leafs it has little yellow spots like nute burn, coco a+b and start up and gh ph down. Ph was 6.5. I only gave minamal nutes temp is at 25 rh 60 and it starting to brown underneath leafs? Any suggestions

Also after they sprouted about day 8 i switched lighrs from 24 0 to 18 6. Should i have left it on 24 0? Until they came on a bit

You can go 24/0 if you need to,it can help keep a stable grow enviroment until they get a little bigger.18/6 will be fine too.
