What am I looking at?
TickleToaststarted grow question 6y ago
Redish Brown spots, and slight discoloration.
Magnesium deficiency? Calcium? Other?
Gave them a splash of Calmag, but was it even necessary?
OR, should I have just swapped nutes and wait, then correct if not improved? (It was nute day, that's why I ask!)

This is definitely going to be calcium-related, but the thing is most of the time with this it's a lockout and the plant isn't getting it all. Yes giving the plant Cal-Mag when you regularly feed is necessary cannabis plants tend to be very calcium hungry. I noticed your ph level was 5.8, In hydro, calcium is best absorbed by the roots in the 6.2 – 6.5 pH range in hydro, it’s generally recommended to keep the pH between 5.5 – 6.5, but calcium specifically tends to be best absorbed above 6.2, so this could be the cause for the lockout.

Yeah you need to add some calmag. See how it goes and add less or more the next time. Cheers 😊

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

Nitrogen toxicity? Or calmag deficiency.Calmag added previous feeding 1 ml for 3L water.
My plants just started to preflower and added 3L water for 3 plants
3ml grow, 2ml heaven, 3ml topmaxx, 3ml bloom
That was my last schedule.
I feed with every watering 2-3 times a week. Most damaged plant is Northern Lights Auto RQ

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.

Brown spots and yellowingWhat do you think this is? Nutrients deficiency or maybe soil ph. Happened overnight and the plants are a little dry but I just gave them water and nutrients. My ph tester has been broken so I’ve sorta been winging it with some ph strips.
