Need some help, I'm really lostHi people, need some serious help here. The new leaves look like sh¡T. They are kinda yellowish and the tops are necrosed. Some spots on the leaves too!
I added some silica in the last water but I don't know if was the cause.
Soil pH varies between 6.5 and 7.0.
Any ideas?

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc.
I believe this may be nutrient burn?
Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.

At what stage do leaves get darker ? This is confusingI overwatered them at the beginning of veg and then I fed them with 0.7 ec nutes max, EC would go up if I gave more. I've had tips burning probably from light too close. I find that leaves are pretty dark but it may be because of the strains. When leaves do get darker in flo ?

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliageAt first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

Popped up around last week (week 4, monday). Prior to week 4, i had been watering with tap water, which in my area is pretty hard.(7.8+ pH) Been correcting pH to 6.8 with each watering since. (2 waterings since then.) Should i just continue feeding 6.8 pH water or add cal-mag?Week 5

The problem in plants when I supplying CO2Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?
