Deformed leaves, consistantly strange shaped leaves.

  1. Hey all, first time medial grower here.
    Iv had some strange shaped leaves recently. From what Iv read it seems to be due to low PH. Multiple strains all experiencing the same symptoms. Most seem to have recovered after adjusting the watering PH to ~6.2.
    Just wanted to get some additional input for future reference.
    Thanks yall, much love. Peace!

    What type of medium; soil or hydro? Soilless, 50/50 peat and vermiculite.
    What brand and type of soil? Black Gold Peat and coarse grade horticultural vermiculite
    Indoors or outdoors? Indoors
    What strain? Dosidos, Amnesia Haze, Silver Lemon Haze, and Sunset Sherbert
    How old are the plants? Half are 2 months and half are 3 weeks
    What type of lights and how many watts? Viparspectra PAR 600 (early veg) MarsHydro E8000 (late veg)
    How far from the lights? 16-30"
    What is your watering frequency and source of water? Every other day on average
    What, how much and when was it fed? NPK? 12ml of Grow/Micro/Bloom per gallon
    What is the medium/runoff pH and PPM if in hydro? Runoff is 5.8 PH and 1500PPM, feeding solution is 6.1-6.2 and ~850PPM
    What are the temps and humidity in the room? Temp is 72-79 F, humidity is 50-60%
    What size pots? 6" pots to start and 2 gallon pots for later stages

  2. I haven't grown soiless with synthetic nutrients in quite some time. But if I can remember correctly, if your run off is higher in ppm and lower in pH, that's an indication that you are over feeding and have some buildup going on. I'd flush, then back off to 600-800ppm for a while. Maybe alternate a plain water day with your feedings
