It looks like calcium and/or magnesium, yes. But it's hard to tell from the picture. It could also be a manganese deficiency if the spots are on the new growth more than the old. Calcium and magnesium would show on the oldest leaves and progress upwards, manganese would work from the top down. Either way, looks healthy and happy, I wouldnt worry too much. Happy growing😀

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. Any idea what could be the reason why my Ph adjustments (BioUp) are not taking effect in the soil. Additional question for SD: What to do with the brown leafes? Remove them?

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.

Lila Stängel - Nährstoffmangel?Hallo zusammen, ungefähr eine Woche, nachdem die Pflanze mit der Blüte begonnen haben, haben sich die Stängel der Blätter rötlich/lila verfärbt. Meint ihr das kommt von der Genetik (Auto Overdose - Divine Seeds) oder könnte es sich auch um einen Nährstoffmangel handeln?

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 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?
