    Default anything wrong with these plants?

    hi lads, this is ma first grow, bagseed indica dominant strain i guess. heres my equiptment.

    black orchid hydrobox 80x80x160cm
    carbon filter kit normally used in 2m tent (loaned from pal)
    viparspectra 300w led (single switch, soon upgrading to 600w model)
    2gal pots,
    verve potting and cutting mix soil (nothing else, no perlite ect)
    formulex nutrient solution (watered at 25% strength, sprayed at 100% once or twice)
    dutchpro multitotal (used once low dose)
    canna rhizo used in early seedling stage
    growth tech ph up down

    my wet/dry cycle is non existant. think its due to the soil and cool lights. will know for next time i guess to start with a perlite mix + maybe some extra household bulbs for warth in the tent. temps daytime have been 18-19c up until i bought my 1ft tube heater. with the carbon filter off the heat gets to 26c. humidity is a bit high at 70% give or take fluxuations.

    not watering till runoff because the soil is not the best and its not got great drainage. plants were given 1l of phd nute water last night (6.5pH, 2.5ml formulex for 2l water.)

    cal-mag arriving today but idk if this will help anyway. have the heater in the middle of the pots to try warm up the roots.

    plants sprouted around 19th december 2018. pictures were taken 2 days ago.

    lights off pics would help, looks like princes livingroom in there

    dont see the point of adjusting the ph of the water in soil imo, i have never had to.

    So based on looks alone, I want to say either Iron or sulfur deficiency.
    Most likely sulfur imo

    Before you go dumping extra nutes in though. How often have you been watering? Because this could be as simple as Lockout or a poor watering schedule.

    Also that humidity is gonna cause massive issues in flower. It's honestly high enough that I'd be worried about powdery mildew even in veg . I try to keep mine from exceeding 60%

    Oh, one more question. Is the yellowing worse on the larger, older leaves? Or the smaller, younger ones? That's real important.

    Usually those defficiencies in soil are caused by over/underwatering and or over feeding

    humidity i honestly dont know how to bring down. my flat has a dehumidifier on at all times set to never let humidity go above 60%. there is so much negative pressure caused by the carbon filter that even leaving the screen on the bottom of the tent open doesnt stop the tent from being sucked in tight. waterin little, like i said this soil has v poor drainage abilities, having to water ever 4/5+ days.
