    Make sure your feed is no more than 6.1 and preferably 5.8

    Start feeding your babies at max 50% of recommended nutes for the first 3 weeks and aslong as your temperature isn't more than 26 celcius you will only need to water every 2-3days. Over watering is hard to do in coco but getting them passed the first few weeks is probably hard because your coco doesn't contain nutes to start with like soil. I'm still on first grow but comfortable enough with coco now.

    Y do you think rh does not matter in veg? I would like to know your views. I would say you wanna keep rh high in veg and reduce as you move on with the grow. Example 70%-80% in early veg and in late flower reduce as low as possible.
    Also with feed strength I would say depending on your background ec depends on feed strength. Also rather than going 50% recommended dosage read the plant some plants can be heavy feeders and some can be light feeders.

    High RH in veg 70-80%, lower in flower around 45-50%. Humidity helps plants transpire so more co2, more food, more water uptake. Low RH will close the Stomata and force the plant to use all its energy to prevent dehydration...so yeah, pretty important i would say

    Maybe I jumped the gun. With my grow I have never monitored the rh until bud and they were fine. Your right it is high humiditity here.

    Maybe I'm lucky like with never knowing ec and still doing well

    But from what I read u wont damage your plants before bud regardless of rh. Just that there is a optimum rh for veg. My rh must have been real high for majority of veg with outside rh at 85% and they drinking 20 litres in a metre each day.

    Only since flower I have worried about root rot and purchased dehumidifier.

    Others have similar setup.and don't use dehumidifier so

    Wont disagree with u guys what so ever just trying to help the guy through first hurdle.

    There's a lot of things to think about and rh was my last one. It's been fine for 2 months without dehumidifier so just suggesting he prioritises others first.

    His seeds aren't dying cause of humidity..

    More likely Temps

    No one like us we don’t care. #upthelions
    Good if no except letting coco dry out will be a major screw up. Coco is very forgiving u can't over water them unless ur completely barmy.

    Read my journal and see my schedule as a noob iv done good

    Thanks for the replies.

    Temps are between 24-27 during the day and 18-20 at night
    RH is between 55-60%
    CFL is a few inches above the plant (it's not hot)
    No nutes yet and EC is 0.4
    PH 5.8

    I know the plant looks okay, but it is 3 weeks old and has not grown in the last week. This is the stage where the plant will fall over and die. They all get to this stage and then stop growing.

    I know it's not the strain because I've had this problem with 1X Jack Herer, 2X Auto Chemdog and 1X DP Twilight.
