Slow growth and leaf problems. Need Advice!!

Discussion in 'Sick Plants and Problems' started by tlgkl41, Jan 13, 2022.

  1. Hi everyone.
    First, pardon my english I am not native.
    I am a noob at growing cannabis, my first grow and first post at community. I wonder why my cannabis plants growing slowly and why my leaves are like that. I done some research but wonder the ideas of experienced growers.
    My setup;
    4x4x7 Grow tent
    Cloudline T4 ( running at 120 cfm at setting 4 goes higher depending on temperature and humidity)
    Mars Hydro Tsw 2000 ( at 24" %75 dimmer ) I tried different variations was better at 20" dimmer somewhere between %70-75 just guessing.
    Biobizz Light Soil
    11litres/ 2.9 Gallons Smart Pots
    Smart thermostat for heater ( Lights on 21C/69F - 26C/79F Lights out 19C/66F - 23C/73F. Heater starts to work when degree get down to min setting and keeps working till the max setting )
    Inkbird IHC 200 for humidity control ( It goes between 60 to 70 for now )
    Biobizz Nutrients
    4x Magnum feminised autos
    Journal till the this day;
    Light running 18/6 Electricity bill is problem for me.
    Water ph between 6.0- 6.3 with adjustment and water temperature 20C/68F - 23C/72F. I use tap water but let them sit for a couple days before watering. Not measured the ec, waiting for ec meter I have been ordered. I will have a idea of ec in couple days

    27.12.2021 > Seeds poppin out jiffy and transplanting to final pots ( should have transfer them to smaller pot first ??
    31.12.2021 > Plain water with 500ml to each pot
    02.01.2022 > 1ml RootJuice 0.75ml BioHeaven/ActiVera 325ml each 1.35lt total
    03.01.2022 > Power failure, only 5.5 hours of light. I am living in a island, 100 meters away from beach and very windy. Power failure is a common thing because of that.
    05.01.2022 > 4ml Root Juice 2ml BioHeaven/ActiVera 1lt each 4lt total
    09.01.2022 > 6ml Root Juice 3ml BioHeaven/ActiVera 1lt each 4lt total
    13.01.2021 > Another power failure. 9 hours of lights.
    My questions;
    1- Do u guys see any problems about grow setup? Probe placement, temperature and humidity settings ? I have 3 passive intake and probes hanging at the canopy level between the middle passive air intake and pots.
    2- Nutrient doses ?
    3- Light distance and dimmer setting ? Pain in the a*s. It would be great to hear from other tsw2000 users. I find some resource that saying autos only need 300- 617 umols for their whole growth not like photoperiods. but adjusting the height and dimmer just guessing and looking the ppdf maps supplied by manufacturer is really tricky. I wrote about it to them but no answer. Lux meter is not properly working for full spectrum leds and buying par meter is very expensive for me, I spend my last money on the setup already.
    4- Leaves craving and curling not staying flat and the colors ?
    5- Plant 1 not growing properly stucked with 2 leaves ? I am really curios about it because it was the best looking with plant 2 when I transplant them
    Plant 2 is looking best out of all
    Plant 3 was always the little one trying to catch up
    Plant 4 looking good time to time ? but seems stunted
    Its been more than 2 weeks since I transplanted them. Am I just overthinking ?? Its been a very long post guys I know but please help if you guys seeing any problems. Wondering your comments and advices guys. Thank you all in advance

  2. Small plant in big pots grow slow.
    Large plants in small pots grow fast.

  3. They grow down below first. If u start in larger pots they have more room to root. But when they start growing upstairs they will explode
