I need help with nutrients

[Growbook318]

I been having this problem for weeks now and can’t seem to pin point it. One of my plants is having a hard necrosis problem(dark brown spots started from lower leaves and is working its way up) with yellowing edges. While another plant has some clawing, minimum necrosis and also yellowing edges.

Using FoxFarm nutrients and following their feeding schedule
Ph- 6.0-6.5
Temp.- 75*F-80*F
Humid.- 60%-77%
Light at 50% with 550 PPFD (PAR)

Yes I use same nutes.
Need the cal mag and also those tops are drooping.
What medium are you using? And how often and how much water?

 

[Airbone]

Possible overwatering?

 

[Growbook318]

I just brought cal-mag for them just under two weeks ago. I use FF Happy Frog soil and I water every other day just under 2 liters and feed every other watering

How much calmag should I be feeding or should I stay following the bottle

What do you use in flower?

I use gh cal mag @ 1 1/2 tsp per gallon but start small. Biggest thing I’ve found is consistency is best.

I would start with a good 3 part nute system and learn to add things as you grow, Vegging plants is very easy, its once you get into flower is where your skills come into play.
You learn as you go is what I did. You have access to a lot of great nutes or learn organics . We never had wonderful things they have today when a lot of us started growing.
