Ok problem solved.The ph of the water i was using was 7to7.5 that was bottled mineral water.

I have just checked my tap water and it has a ph of 6.5 to 7.

I think the best thing to do is move the plants to the top soil.Give them a diluted 1/6 strength feed and hope for the best.

Is it worth doing this or will the plants die?
privatepile Reviewed by privatepile on . Yellowing Leaves(I have researched) Ok i have a problem with my plants.The bottom leaves have started turning yellow. I have Top Soil(no ferts).The strain is White Widow.They are under 3 x 40watt daylight CFLs,They are a few inches from the plant. There is a fan blowing on them. To water i use bottled water so the PH should be fine. I have researched a lot and i think most of the time its nute burn. Rating: 5
