hey there it's potassium deficiency, you can see because the veins of the leaves stay green.

Bottom leafs getting dryThe last two pictures show some sights of deficiency after getting a little bit dry before repotting. Any recommendations: should I do something? I will definitely use some ph-down and water with 6.0 to 6.5 ph to help the microorganism get going :)

I don't think this is nute burn...So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

I see that there are yellow leaves with brown spots, the tips of some leaves are "burnt", and I also could see very small flies
I think they were "Fungus Gnats" and that they may be the cause of his yellow spots, am I right?
and how many weeks would you wait for the harvest? thx!Week 8

Nutrient problem??? Excess or deficiency?What do you think is the leaf issue?
Open to second opinions.
Most everything stayed the same, except:
> increased water: 2L to 3L per 7 gal of soil
> introduced a bloom booster
> increased volume of worm castings, molasses, mycrobes and ethylene to the tea

Leaf identifyThis is my test plant.
Please help identify leaf. This is nute burn? Top of the plant look just fine. Should i worry?
Before this happen I feed her 570ppm and try supercropping on main stem (twisted). She fine with 660ppm in the past so I confuse what is the problem.

What am I facing? Plant is getting worst everyday, and I can't find the reason why. Thought it was a calmag def, but now I don't really now.When I switched to flower, I started watching some rusty spots on the leaves of the gelato.
After doing some research, I thought I was facing a calmag deficiency, and starting adding some calmag.
Plant is getting worst, I flushed the roots and water between 5.8 and 6 as canna ask

What to do? Leaves are getting worse.Had some light strain earlier on, but now im leaning toward a deficiency. Been feeding on a low-dose flora series schedule with clean ph water for every other feed. Just had clean water yesterday and nutes 3 days before. Dry out between feeds. Nitrogen? Calmag? Other?
