Calcium deficiency. If nutrition mix is too strong it will lock out others.

New growth with yellow on the leaf edges is spreading. I have moved the lites to 12", the only change has been from using distilled water for the 1st 3 weeks then started using filtered well water (high sulfur & iron content) Should I switch back? Where to buy?

She has yellowing and dying leaves issue for a while now. I was giving more nutes lately to combat the issue. Now burnt tips say it is to many nutes. So I decided yesterday that I should water with a bit of calmag before next feeding at beggining of the week.

Deficiency or Burn?
I have used Happy Frog before with no issues. I am running my first 420 Fast Buds seeds and they seem to have nute burn for the last few weeks no matter what I do. Is this maybe a deficiency and not burn?

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.

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Slight leaf tip "burn"
What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 1000

What is happening to my plants?
I had them in the terrace outdoors. Temperatures sometimes reach 40C. Lately more and more yellow leaves in the ABC have been showing up. In the other normal leafed plants crispy dried and brown leaves are showing. Now the ABC also is showing some dry leaves and yellow as well.
