I noticed this the other day so I added 1ml of Biobizz calmag per litre of water for the first time yesterday. I'm in a hard water area &I asked on here recently whether I should feed only magnesium as there is so much calcium in my tap water? There are literally shards/pieces of calcium in my kettle. Any opinions would be great They are 14 days old in Light Mix soil & under 2 x 125w LED's. They were fed yesterday with: Each plant got 2 litres of water with 2ml Voodoo Juice, 2ml Tarantula, 1ml Fish Mix, 2ml Bud Candy, 2ml Bio Heaven, 2ml Acti Vera & 1ml CalMag per litre of water. Any help is much appreciated
They look great to me.........I don't worry about a few spots on a leaf. You don't have a calcium or magnesium deficiency.
as the other Guys have said them marks or not cal/mag deficieny so dont worry ....plant looks good ...mac.
For my last grow I lst'd them. But I thought I'd just let them grow & cut the odd fan leaf off that was covering too many buds.
