Yes dark tips

ignore cal def..
how much calmag do you use?
otherwise just gaia green?

 

[GNick55]

how are you using the gaia? and with what medium?.,
this looks like serious over feeding, which is causing the spots..

 

[GNick55]

and than fish fertilizer?
how much of that did you use?
what kind of fish fertilizer or what is the npk ratio?

Calmag 1teaspoon per 2 litters
Giagreen was amended 2 transplants forgot last so I added a 1teaspoon of fox farm/ gal and fish fertilizer at same measure

you over did it with the calmag, firstly doesn’t need until 3-4 weeks into flowering but alright to give 1 ml per gallon until than.. you gave it 10 ml per gallon.. also the fish fert at 5 ml/gal you have is 5-1-1 and guessing you also added fox farm grow big 5 ml/gal ?? 6-4-4..
also what grow medium are you growing in?..
you over did it on feeding..
what are all the nutrients you have there?

I agree and I know some people don’t agree with flushes but I would say to give your plants a flush. I’m also a new grower and I did the exact same thing and over fed my girls In veg and had to flush to correct it. Took em about 4 days to recover and like 6 days to finally dry out the 3 gallons pots they were in.
