Calcium or Manganese deficiency?

WulfBludstarted grow question 2 years ago

Calcium or Manganese deficiency? Last week had what I thought was early calcium deficiency. Gave it a dose of CalMag but now not sure if it’s still Calcium or possibly Manganese.

You probably confused Manganese with Magnesium.

Leaves turning yellow and dying I have a plant that gets a lot of rust spots, even though I give it CalMag once a week. That plant also started getting a handful of leaves that turn yellow and fall off. Is there a nutrient I'm missing in my regiment? Should I do CalMag every watering for the rust spots?

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliage At first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

PH-Problems in Soil Before repotting, the pH value in the soil has always fallen to below 5.5. The plants always have an iron deficiency. I then repotted the plants and that worked well for 14 days. Now they are showing PH deficits again. The soil has PH 5,4 -4,8. What could be the reason?

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? Th Is this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

Leafs losing Color, die off.I could really use some help recognizing if and which deficiencies the Super Skunk has. It's currently growing in an organic soil that's been pre-fertilized and should be enough to complete the cycle. The temperatures are around 23c (73,4F) day and 19c (66F) night.

Ph value is decreasing despite BioBizzUp I don´t get it I´m trying to increase the Ph value but it is permanently falling again to a value of 4,2.

Are those nutrient defficiencies? Which ones?A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).
