Calcium excess.. Check your local water report.. See how much calcium you have in your water to begin with.. Use cal-mag more sparingly..

Do these leaves look okay on my Auto NL plant?Can someone please look at my Auto NL, and tell me if the leaves are looking discolored or if something else is going on? It's probably nothing but I feel like a concerned parent lol. We had given it maybe 1 tsp of voodoo juice in the soils pre-soak session before germination.Week 2

Stunted plant - Leaves are blotchy and wrinkly - Problem identificationMy stunted plant is recovering i guess, looking better than a week ago and is growing bigger slowly, but the problem has to be identified so i don't make that mistake again. The leaves look as stated, light burn looks alike but i'm not sure since the other 3 had the same distance3y ago
