  1. Hi everyone!

    I have a problem with my plants in the 5 week growing stage.
    The environment is 600 hps lamp and temp is 22-27 celsius in the grow room. Use soil 14liter pot and i add 500-600ml water/plant two or three days with 6.2-6.3 ph and ec is 900-1000ppm. I dont know why curling the leaf and why yellow the new sprout.

    Yesterday i added epsom salt and calcium to my plants.

    The last week i add just one time ph water with superthrive that dry the soil.

    Is this zinc or iron, sulphur or maybe nitrogen and basic nutrient definiency?

    Or just underwatering?

    Have i magnesium and calcium definiency?

    Thanks in advance!
