    Default Wilma grow problems

    Hi guys hopefully I'm posting this is the right section as I'm new to forums 🤔


    I'm currently on my second grow with 1xcheese #1 and 1xgelato. Second week of flower.
    1m x 1m
    400w mh for veg 400w hps for flower
    Lumii aero tube 5 inch
    5 inch ram extraction pulling through carboair filter
    4 inch intake
    Wilma style set up
    Scrogged
    Using shogun nutes apart from the buddhas silicon
    DNA coco/cork

    Couple of issues I'm running into which will be answered easy for pro growers.

    1st..
    I'm experiencing high humidity 60% with light on and 75% with light off. My temps are 25°c on and 20°c off.
    And that is all with a dehumidifier on 24/7.
    This is obviously bad news being in the second week of flower.
    How can I get it down please help haha....

    2nd
    I'm getting a white residue it the bottom of my tank which when I agitate turns all the water cloudy. I do have an airstone 24/7. And the water has only been in 2 days
    What could this be???

    3rd
    My dripped keep clogging up with what i presume are tiny bits of coco and ways of preventing this.

    And help would be much appreciated cheers 😁😁

    1. Humidity all around the UK has been insane. My outside RH was/is 86% Keep your girls well ventilated with lots of air flow and they will be fine. Second week of flower is not the big worry. When you are in week 9 of 14 and your buds are big, tent full then worry. There should be sufficient gaps around the stems and below the canopy for good airflow mate.

    2. What is your PH?

    3. Put some kind of fine mesh on your waste line to act as an filter???

    Cheers viz...

    Yea rh is sky high at the min I'm considering slight defoliation but don't want to stress them too much because they are doing well in general.

    Current ph is 5.7 in my tank.

    Yea maybe some of the Mrs tights might work as long as it doesn't restrict the flow

    2. EC of your water before nute, and EC after you have added the nutes.

    3. Tights work fine. Your coco should settle down if you have packed it in firm enough.

    Ec is something ice not measured up to now. I know I should be and I've ordered the meter of Amazon just waiting for it to come. What should I expect to see

    Check out these, you will be able to get reducers etc to make it work

    Well it is really all depending on your water, so my starting EC is 0.2 and I seldom go over 1.2 even in flower. Mainly because I subscribe to a more is less philosophy when feeding cannabis plants. The recommended dosages on the labels are way way to strong in my view.

    What do the tips of your plants leaves look like, I know you can not post images yet. Is there a difference between the tips of new leaves and the more established leaves?

    Hmm ok I'll know more tomorrow when my meter arrives.
    The leaf tips look great overall the plants are very healthy and are good sized. With the Wilma only being set up for 2 days time will tell I suppose

    I've been told it could be salts in the tank from the silicon and I've caused a calcium lock out??

    Confused now, your plants are 2 weeks into flower but only 2 days in a wilma?

    How were you growing, and more importantly how were you feeding your plants before?

    Ahh ok so.... I started by hand feeding until 2 days ago and due to my low scrog was having trouble hand feeding so I brought a Wilma set up for 2 reason... 1st is it eliminates hand watering and 2nd my next cycle I want to use clay balls instead of the coco I'm in now

    Thought you said you had calcium lockout?

    Get some pics up, your residue I’m unsure what that is, advice would be to get a decent air pump and check the temps of your tank ( temp of tank is extremely important )

    Well it’s all bloody important, once you have it all dialled in they will grow fast

    Just a thought but i had the dehumidifier you have and i found it useless to be honest you need a bigger one, i got the £130 one from screwfix and its the best thing ive bought always keeps RH between 50 and 60 if you want it lower you can set it to be on all the time
