Hey gromies, I'm having trouble identifying these issues. I have 2 plants indoors under 2 600w LEDs in their 4th week. Growing in coco and feeding them Flora series with added calmag. pH at about 6.0-6.1. I think it has a calcium deficiency but not sure what the yellow spots are

well looks like youve had some PH fluctuations, and thats the response of the Plant. Showing those discolorations. It looks like alockout of iron and magnesia.
Be sure your Ph is " stable" and continue feedingher. I checkback the growdiry

it seems to me that there is a lack of calcium which at this stage is the most common but it could also be chlorine in tap water if you use it, leave the water in open bottles for at least 5 days without being exposed to sunlight, the chlorine ends up evaporating from the water

Yellowing leavesLower leaves are turning yellow, these seem to be one that are hidden a bit from sight, so possibly not getting enough light, but it seems to be spreading, and one of them has fallen off. Is this some form of nutrient difficiency, or something simipler?

Lower leafs getting yellow tips and spotsI just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake.
They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.

Yellow tips at bud-leafsWhat is the worst case of what could happen to the buds and the harvest due to the yellow tip burn?
Since 5 days the near leaf buds have yellow tips.

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?

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.

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.

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?

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.
