Calmag Deficiency? Yellow Spots
dusterpstarted grow question 4 years ago
Last res change I saw some yellow/brown spots on the fan leaves up where the main cola was getting too close to the light. Is this a calmag deficiency or light too close? I moved the light up to the top of my tent with zip ties and got back several needed inches. See pics.

Looks more like calmag but if its starting at the bottom leaves then you should consider a lack of potassium, when its at the upper section that's when its calmag.
Stay lit growmie, doesnt look like light burn.

Moving the light was a good call. In flower with that light, you want to be around 18 inches plus or minus a few. You can also try feeding at a ph of 5.9 for a few waterings. Happy growing.

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flowerThe odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Yellowing, wilting, stunted growthCan anyone please help me identify whats wrong with them. I've done a flush, adjusted the lights, reduced the nutrient strength, I've pretty much done everything and still stunted growth and they are still looking weak and frail. I'm lost and I don't even know what's wrong.

Is it time to feed nutrients now or can I wait?I have not given any nutrients yet but I'm wondering if I should.
1. Are these really signs of nutrient deficiencies?
2. Which nutrients are missing?
2.1. My guess is P, N and/or Mag, Cal. Is that a good guess?
3. Is BioGrow a good choice to address these deficiencies now?
