-6" fan blowing over the t5's phresh filter and 190 cfm fan thats only on at night for 6 hours to keep dark and very low power (i have a fan speed dial)
-No nutrients yet other than the great white root enhancer i used when I planted the seed.
-I water them lighty every other night but one of them seemed very dark green and swollen so I thought I overwatered. But now 3 days later after next to no watering because of my fear they are now 7 days from poking their heads out of the medium and the leaves around the edges of 4 of them are lightening and cupping slightly but two of them the leaves are turning ashy at the tips light brown burnt look .....wht am i doing wrong???
