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?

Could someone please explain the precise mechanism underlying the phosphorus anomaly? As anticipated, availability decreases with increasing pH, yet it exhibits a sudden surge at pH 8.5. What is the exact (bio)chemical rationale behind this phenomenon? Boron has a similar pattern

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?

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

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?

Fixed soil PH: Now from young leaves' interveinal chlorosis to all over light green
Soil 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 day

Please help identify the cause, interveinal chlorosis since 2 weeks old, no necrosis so far. These two plants are 26 days old. Do they look stunned?
Is this magnesium def since it's going from the bottom? Is it possible the first signs started to show when they were just 2 weeks old? Or is this iron? Or is it smth else? Calmag given two days ago. Pistils show already. I water with ph6.2 but no runoff yet to know the soil ph.

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.

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).

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?

LSD Auto BarneysFarm is showing nutrient deficiency. I need some help to get this girl unstressed.
I'm using BioBizz LightMix with the BioTabs Starter Kit in 25L pots (prepared the medium from the beginning with 3 biotabs). I have three girls where 2 of them are running healthy, only the LSD Auto is making trouble. How can I fix the problem which you can see on the image?

Nitrogen Toxicity?
Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.
