    Can anyone give me advice to help identify my problem ? At first i definitely had to high of a ph and i got that fixed up but the edges of my leaves are curling over .. im at 62% humidity and 80 degrees Fahrenheit, i water only when soil is dry, i poke my finger in the soil to the first knuckle if its dry i water. and this is a auto flowering plant that's why its a dwarf

    the leaf edge curl is usually caused by either too much heat, too little humidity,or too much direct air flow, or a combination of the three. possibly your light is just a little too close.
    the rest looks like you just need a good shot of cal-mag.

    yes, that will work. while it has N, and Fe, its primarily Calcium and Magnesium. add it to your water and ph it to 6.1 before you water with it, the best range for it to be absorbed

    Also led lights usually need to be higher above canopy most are supposed to be 2'-3' above canopy so my thoughts are light to close to canopy

    i think i meant to say these are cheep lights and i don't think the wattage is correct who knows .. so i figured id go closer in case they are indeed that cheep and labeled wrong :shock:

    I had a fairly cheap 800 watt led by king it was on around $125.00 it says 3' above canopy i tried lowering it once and my leaves curled and burnt looking just like yours. Thats my best guess

    Your welcome.. good luck... After growing with led for about 4 years im going back to mh/hps better quality buds and plants overall. The LED s tend to keep buds more airy and lighter.... I just cant afford the quality LED lights out there..
