thanks,
i mixed some castings after transplanting, before i had used just a soil.

the nutrient i use for veg seems to be right, the info and dosage on that link is wrong, sticker is saying every watering, 4ml if deficency,2ml regular. Im following plagron schedule to.

begbie5 Reviewed by begbie5 on . black spot, shadow Hi to everybody My name is Dan i have a problem with my 3 week old plants. I grow them under 600hps, 12inch from a lamp. I had a small deficiency of N few days ago, but that problem was sorted. Ph of soil is 7, water between 6-7 (do my best to reach 6.5). there was a problem with humidity so started spraying leaves with water for a night. I did it every night and started 3 days ago. I sprayed the well with a water. Today morning one plant got some black shadows/spots on bottom leaves. Rating: 5
