From your second pic.
1-nodes not elongating, bunched up top phos among other potential reasons
2-red leaf stem phos lacking. Many reasons...
3 leaf curl up. VPD, magnesium, too high pH?
4 necrotic spots on older leaves first..
5 dark green veins light green leaf. Worse on older leaves but shows also on younger leaves.

so i need to lower the PH of the water. i haven’t been doing PH. i’ve been adding 1ml silica and using tap water. so i know the water i am using to water them is very basic. i didn’t think that it would cause this bad of an issue not checking my ph and making the water more acidic

Silica is raising your ph
I quit using it and stopped worrying about ph afterwards

First off. Answer my questions.
What is the media?
If soil, WHAT soil?
List any modifications you may have done to the soil.
What are you feeding?
How much ?
How often?
Silica is NEVER useful in SOIL growing of Dicot plants! Cannabis IS a Dicot and Dicots get ALL the Silica they can use FROM the soil!
Don't be sold a bill of BS "goods" by nutrient makers!
Now if your doing a soilless run. THEN the use of Silica is a good idea... ANY type of hydro should have Si in the mix..
IF you use SI in a hydro style run.
Mix by adding the Cal/Mg first - then the Base - then the Veg or Bloom - THEN the Si last. You SHOULD MIX WELL AFTER EACH PART IS ADDED!
I suspect underfeeding first.

i’m running ffof.
i’m using dr earth flower girl dry amendments and EWC.
they are mildly hungry for more N BUT my biggest issue is SAVING them. so i am cutting Si out of the feed. i will up the N intake and i am watering when top inch or so is dry.
this is the first run i’ve experimented with dry amendments and not phing the water so this is experimental. now i understand they’re underfed and the ph is too high.
so i’m going to add more EWC and feed and then i’m going to stop using si as well.

I like an N value delivered at 6 or a bit more in veg. I only drop it to 4 in bloom...
Good luck

yes i got the flower girl because i was going to flip. then i had this ph issue and it hasn’t been getting better because i’ve been using silica in my feed and my water is VERY basic.
i have another dry amendment feed that is like 8-10-6 or something along those lines. i’ll get the N back up and remove si and should bounce back
