Rusty brown spotting on upper fan leaves, too much Tiger Bloom or deficiency?
Hindu auto, week 11 started seeing rusty brown spotting on upper fan leaves. At this point I was only using tap water and 4 tsp/gal of tiger bloom. That is aggressive so I backed off to 1.5 tsp. I watered with cal mag 1 tsp just in case it was deficient. Ideas? Buds seem ok.

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.

Discoloration bud leaves
Anybody know what this discoloration is? Humidity was a bit too high so I'm hoping not some type of mold. The affected buds did get quite a lot of wind and light, so it might be light- or windburn? Any help appreciated!

I flushed it because some leaves were showing some Nitrogen Toxicity. Run off was coming at 3000ppm and I fixed it to 1500. Now the older fan leaves are yellowing with some brown spots (check the last picture). It's a deficiency? Should I increase nutes? Thank you very much!

I water my plants everyday , however I have mixed my nutrients “ph perfect grow, micro, and bloom” in with my water only the appropriate amount given on the bottle. Should I be using water with the nutrients everytime I water or switch it up with plain water as well?

What is causing my leaves to turn dark and dry?
I'm growing 3 Gelato #33 plants in a DWC 5 G bucket setup. Same conditions for all 3 plants, but one of them is experiencing dark spots on the leaves and now they are beginning to shrivel up and dry out. The newer growth looks okay, but might not last long. What can I do ?

What nutrient deficiency is this?
What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Was ist das?
Meine Gorilla Skittlez (siehe Tagebuch) wird relativ hell und bekommt komische Flecken. Ich gieße abwechselnd mit Hesi Bloom (2,5ml/L) , 1ml/L Calmag und nur Calmag 1ml/L Dachte die Flecken kommen von zu wenig Calcium Magnesium. Jetzt steigt aber mein PH Wert von 6,8 auf 7,4.

Any idea what I might have done wrong on the sick mothman maybe nutrient lock or overwatered? It was the only plant without drainage hole and stayed pretty soaked as I was out of town for 3 days. Any advice is appreciated!

When growing different strains in a RDWC system how do you balance plants with different nutrient needs. My amnesia auto ran into a major cal-mag issue and now is experiencing nitrogen toxicity, while my feminized Jack Herer's are largely unaffected. Thanks for the advice.
