This girl (PPP) started to get yellow spots all along the edges.. I flushed her out a week ago but it seems like she's just getting worse.. Any help would be greatly appreciated.. Ph is at 6.5 and I haven't added nutes do to the fact I used mg moisture control soil for this grow and it has that time released plant food.. I know it's not the best soil to use but the nearest store that carry's any good soil is like 400 miles away..
She is around 4 weeks old vegging under one 400 watt MH.. The new growth hasn't been affected only the older leaves.. Other than the spots she's still growing very vigorously... She doesn't droop at all but is growing alot slower than the others.. Like I said any help would be appriecated...
