Hi all. Just a quick one.
Do I need to use calmag on every watering using a sf4000. It's my first time using a led. Thanks for any advice. 👍🏻👍🏻

Depends If coco is present in your substrate. If so then I would use it more often then not coco absorbs cal mag.

Hydro. If the plant is overfed, can the ec possibly go down when they are given new nutes ?Usually they eat 0.1 ec when I add nute or with a new tank and ph goes up. Then it stabilizes and ph starts to go down till I refeed since I have a small tank. Right now there maybe a nute block but EC still goes down like they are hungry... Hydro with a small tank is confusing..Week 9

Нлвые проблемы с переводом на цветениеЗаметил побеление на кончиках листьев. В основном на нижних, но есть и на паре верхних. Не могу определить, то ли перекормил, добавив Bloom booster, то ли дефицит калия и кальция с переводом на цветение, буду рад любым советам и адекватной критикеWeek 8

Should I wait for deficiencies to introduce more nutrients? I haven't given these plants any of the A.N. veg nutrients that I have for them. We are at week four today. Maybe there are deficiencies that someone could point out to me from my photos?Week 4

Calcium in tap waterIs 95mg/L calcium too much in tap water? (It's probably a little lower than that, since that's exit measurement from the waterworks.)
I haven't seen any signs of acute calcium toxicity, but I'm worried about buildup.Feeding. Chemical composition

PH all kinds of fucked up!Urgent update. So it turns out the issues all alone where the soil ph which after testing it was PH 3.2 😳
I have flushed with ph 6.8 water and then added some epson salts bringing the final ph back to 5.6-6.2. I then topped the pot with new fresh compost. Will she survive?Week 9
