I would doubt it at this stage of growth. Other reasons could be light or heat stress or ph in balanced

To me it looks like potassium excess, not a deficiency of any sort. Decent soil will still have ample nutrients for baby seedlings, and at this age.

Cal/mag problem or heat issue?
A few leaves have some problem spots popping up here in week 6 (see pics). No nutes, PH’d water. FFOF/HF/Perlite mix for medium under 20 hours of light. I’m guessing either got too hot from being in 90F heat for an hour or needs cal/mag? Any advice from any veterans out there?

My leaves on plant getting yellow at week 4. Gave her a flush for a few days with a pH of 6.0 but the run off stayed at 4.8. continued flushing with a high pH of 8.0 then the run off went down to 5.8. I did add peat moss to my Coco/perlite. Could that cause the pH to be low?

Duda puntas quemadas o stress luminico
The tips of one of my plants are burning, but I don't know if it's due to light stress or excess fertilizers since I have All Mix... it only happens with 1 plant and a few leaves. It's worth noting that I used to have the light at 35cm. auto, 28 days,

Browning of leaves, heat burn or pests?
Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.

What is this deficiency with DWC, GH Trio, flower day 19
I'm in about day 19 of flower and a deficiency just showed itself in the last day or so. It's in the last 3 photos of week 3 of flower in my journal. Any ideas on what it is and how I could mitigate the problem? Grow has been essentially flawless up to this point, thanks!!

Maybe PH Lockout?
Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.

Biological Cal/Mag alternative? It appears the cal/mag from BAC is mineral feeding, is that correct?
Starting to see what looks like a deficiency of Cal/Mag. I'm trying completely biological and I can see the Cal/Mag under the mineral nutrients tab from B.A.C. Is there a biological alternative?

problems with low leaves
in the lower part of the plant some leaves are yellowing, others are drying out and even detaching. can it be due to the fact that since flushing (a week ago) I have not given anything to the plant anymore? I hope this does not compromise flowering

Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!
