Hello Guys this girls are in week 3 of flower . I’m growing in coco Using 5 gallon pots . I’m feeding 10 mil per gallon of each mills a and b , cal mag 5 mil per gallon and big bud 2 mill per liter . Temperature with lights on is 75-79 Temps with light off 65-71 . My humidity is around 50 . It looks like nitrogen toxicity or maybe nutrient lockout ? I’m feeding at a ph of 6.0 . Some of my plants do dry pretty quick. Runoff ph is 5.7.

Yeah you should have a wand that checks e.c; easier to manage and know when you're putting into the feedings; plus over time salt builds up so you need flushes with lower nutrients; I wouldn't be surprised if you were by 3.0 e.cs, but your stems look super green and nice

Nute burn

Water til run off between feedings. More run off than with feeding.

Looks like a fresh feeding a couple of days later. Giver a 5.7 tap or RO. 2 gallon shot then give it 1/4 strength this time.

1/4 strength AN

Looks like nutrient burn to me.

Honestly on some plants I don’t really get that much runoff . Some guy just told me that if I don’t get at least 20 percent runoff the plant will eventually get nutrient lockout .

Ima give them ph balance tap water . when should I start feeding again ?

My ec should be below 3 ? Sorry don’t know much about ec . I will go get a wand at my local hydro shop .

EC or PPM meter. Either is fine

This is the tricky part no nutes isn’t good either but if u flushed then you should be able to go 1/4 strength.

Guys so I been feeding at a ec of 0.8 and with a 6 ph my runoff is reading 2.0 ec should I keep flushing ??? Pretty sure is a salt build up

Seems like it. I shot mine in the tub kept adding plain tap water and draining till the water came out clearish. I think I used 6 gallons But I just kept dumping and draining. Ph’d last 2 gallons then added my nute mix.
