Hey, to me it looks like you sprayed your plants with something during when the lights are on. If so, you should never spray plants with lights on, always have it off. Nutrients burn leaves under the light.

Normal or should I be careful?🤔
First time I see these little dots on the leaves, can anyone identify them or is it nothing to worry about, as I'm thinking? 🧐🤔

Root rot or pH imbalance?
This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!

Interveinal chlorosis and dead spots on leaves, deficiency?
This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

Look At This Pigmentation!
Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding. . , , , . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ?Why?

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same. I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Calcium Deficiency???
So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

Sick plant, could be temp, nutes, too much water?
Leaf tips looking burnt and wilting in flower ... keeps getting worse no matter what. pH 6.8. Raised light. Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

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.

Brown Spots on Leaves
I’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Calmag or Potassium deficiency
Starting to show hard yellowing on plant #2 looks like it can be calmag Deficiency or Potassium Deficiency. I gave them a bit extra calmag a few days ago and it seams like things are not improving too much.
