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.

Ph value is decreasing despite BioBizzUpI don´t get it I´m trying to increase the Ph value but it is permanently falling again to a value of 4,2.
Any idea what could be the reason why my Ph adjustments (BioUp) are not taking effect in the soil.

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.Leaves. Dropping off

Fixed soil PH: Now from young leaves' interveinal chlorosis to all over light greenSoil Ph was off: 7.1. Switched to phosph. acid and use Epsom salt. Now: 6,4ph, Ca/Mg ratio at 3:1 (instead of 11:1). Used foliar spray (GH Enhancer). Ladies still show deficiencies: Now all over light green. Didn't feed Bloom due to overfeeding in grow. Will give Bloom in two day23 days ago

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 foliageAt 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?4 months ago

PH-Problems in SoilBefore 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?Setup. Substrates

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? ThIs 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. Thanks4 months ago
