Hi mate, first check you ph to be at right range, and secondly add cal mag (which I think is the problem)

Ec rising in hydro (6th week flowering - closed circuit tank and drip)At the end of every day, EC rises by 0.2 at least. Starts at 1.60 and then in their evening it goes up to 1.83 ! So I have to add water (2L) in order to go down. Does it have to do with the fact they had overfeeding, toxicities and deficiency so they don't feed well ?

Unsure about waste of time without any nutrients I keep seeing people say I NEED nutrients but I can’t get any. Is it not worth it without ANY nutrients? I can’t afford anything, not even calmag stuff. I’m thinking anything under 10grams, I’m just not going to bother let me know what you think.

Yellowing too soon?What do you think about the yellowing on the 6th week? The npk of the soil i use is 9-2-2. But its the king of yellowing when she needs more N. No dark spots, no burnt tips. This would be normal maybe on the 8/9 week i think.
