HELP PLEASE! GGA week 4 of flowering, idk what to do!

[Cvntcrusher]

djents!

details:
gorilla glue autoflower (she’s just starting week 4 of flowering)
under 2x 100W QBs
3 gallon wide plastic pot
FFOF
temps 77-80° F lights on 70-72°F lights off.
RH 40-50%
on 8/18 she started minor yellowing
8/21 i gave her 6tbsp of flower girl and 5 tbsp EWC.
8/23 i fed her some liquid nutrients.

PH of water and nutrients 6.4-6.5

watering when dry. i always lift the pot and check the top of soil.

i’m not being impatient, i’m wondering why the problem isn’t getting better. i know the dry amendments take a few days to break down and start releasing nutrients. but i have fed her liquid nutrients 2x actually. once before top dress and once a couple days ago.

what do i do?? i know autoflowers are risky in a case like this. i don’t want to lose all this foliage and fuck her up..

uploading pictures from 8/18 until today.

please help me, i’m trying and apparently failing.

i was growing in coco. by myself for awhile. using silica, calmag, & 3pt nutrients.

i moved and started a new garden with two roommates and i tried to cut them in and give them some responsibilities. by doing so it really fucked up my grow. numerous reasons why. so between going back to growing in soil and not doing everything myself.. i lost a few steps along the way.

i remember now though.

so going forward with my ffof grows, around day 30-35 from sprout i need to start feeding nutrients as well as calmag.

it’s just a little different switching back to soil because in coco i never used more than 5ml per gallon of any feed. in soil you can use up to 20ml per gallon with varying factors obviously.

but vine vitality just sent me their bucket that has all three parts and calmag. so tonight when i feed my GGA and make the water for my garden i’ll be adding calmag. almost all of my plants have a calmag deficiency lol

Cuntcrusher, your plant needs more nitrogen.

 

[hotrodharley]

Needs a good veg feed with cal mag.
