Rooting but not growing...

Ok I'm running a CAP EBB flow system using hydrton as medium. Have clones in 2 inch rockwool cubes. Most of my girls are looking good and a few have a decent root system going but they look weak and are not growing at all. In week 2 of veg. Some even are rooted all the way down... Temp 76 lights on and 73 lights off. Humidity between 35 and 45 %. Using advanced nutrients using the Lucas formula and co2 with ppm of 1200 when lights on and exuast fan off. What's going on? Thanks all!

if they are still rooting and not vegging you are not in any week of veg...try not to count weeks, it just makes everything seem longer. give them time, they usually like to build a solid root system before the leaves take off. if the roots are white and growing they will start to grow dont worry. patience.

ps. dont use any nutrients, they dont need them right now your just wasting them...same with the co2..they cant use it anyways so why put it in there...that stuff is for later

no. some may argue that a particular range is ideal, and maybe it is, but you're fine. try not to let it get much warmer than 75.

i've always noticed that the plants seem to take 3 or 4 days to respond to changes. that's for both soil and hydro. if you changed something a few days ago or if you stressed them out a little bit a few days ago, they may take a few more days to get going again.

your signature says it all: don't overthink it.

this is normal (runts) it happens, this is why i take 50% more clones than needed that way i can pick the quickest/strongest rooted clones of the bunch. i get 100% success on my cloning but 50% usually root faster and veg quicker after planting.
