i bet you used mg soil or a soil with a time release nut. if so thets your problem over nutting. justflush with ph'ed water and cut the dose in half if you are in fertelized soil. if not when did you start feeding your girls.

yes it was a pre- fert. soil dont no how to flush? new at this can you help me out really am having fun with this and dont want them to die?

i started when they were 5 weeks? only feed them twice

just water with plain water for a few waterings but ph the water before you do. i recomend not to use a fert. soil for that reason. you really dont no what you feeding then and you will over nut every time. good luck. after you water a few days check the ph in your runout and see where its at. you want it to be 6.0-6.5.

first pic looks like over moist soil, second looks like it might have a slight ph prob,do all the plants share the same feed ?

yes they all have had the same? water them together when the soil cracks
