Right now your lights should be 18/6 or 24/0 for vegging. Either one is fine but stick to one through the vegging stage. Once the plants are big enough and mature enough ( usually 12-15 inches tall) you then turn the lights to a 12/12 cycle. This forces the plant to start flowering ( making buds). You keep it on 12/12 all the way to harvest.


lol it is kinda confusing but it's ok because im getting good advice still. My problem now is that I want to sex them now because I don't have a big grow space and I have 5 plants in there now and I need to start doing some eliminating lol. will 18/6 cause them to show sex within a week or so? They all have 5-6 nodes on them. my tallest one is about 9 1/2 inches tall. they will be 4 weeks old on Sunday Feb 28th.
Another question I have is there a few leaves that are starting to curl or turn yellow on the tips. I am assuming this is a potasium deficiancy but not certain. Would it hurt the plant if I trimmed the tips of the leaves where they are turning color or curling. Thanks again.
