    Calcium or beginning of phosphorus

    thank you. I was trying to get the root system developed enough for a 3 day water before repot. It’s still taking about 7 days to dry out. No perlite in it. It’s been stunted for a while. Will the roots not grow enough to a 3 day water schedule before I repot it? I’ve had issues with...

    Jack Herer tip burn all leaves and lower leaf chlorosis

    Thank you. How do you know it’s magnesium? I thought tip burn on every leaf was over fertilizing or potassium deficiency. I also did half dose of cal mag last watering.

    Manganese or calcium deficiency?

    Hi sorry the shiny leaf is because I foliar sprayed before the picture. Last watering was 1/3 dose fish seaweed with cal mag full strength. I don’t have a pen. This is a soil grow no top dressing. Watered until good amount of runoff. Water always ph to 6.5. I will try what you recommend. Thank you

    Potassium excess?

    More perlite? I figured once the roots grow the plant will require more water and that will reduce watering time. Is this incorrect?

    Potassium excess?

    3 gallon but takes a week to dry out so I was letting the roots develop so that the watering is every 3 days before potting up

    Potassium excess?

    One area blowing somewhat over the top, but almost all leads have burn on tips. Been giving it potassium silicate because stem would fall over when it dried out.
