6000w Grow Nutrient Help w/ Pics

High,

I've been trying to figure out what these plants want (please see pics). This is a 6000w air cooled system.

This is a Prop 215 grow in California for our patients. The plants look like they have a Nitrogen deficiency but I've upped it with no progress yet. So here's the setup:

80F 40% humidity

Week 4 of flower. FFOF in 5 gallon bags.that keep frigin drying out and having to water every other day. The schedule goes like this: feed once a week, water, water/molasses, water, feed.

Strains:
Lemonade
Tangie
Gorilla Glue
Chocolate Hashberry
THC Bomb
Chiesel
The White
White Buffalo
Chem 4

This is the 3rd run in this room 1st time with 6000w, originally I had it set to 3600w with no nutrient problems.

Nutrients:
Earth Juice grow
Earth Juice Bloom
Bone Marrow
Cal-Mag
Molasses
Meta-K

Last feeding amount hand-watering in 5 gallon containers:
Earth Juice Grow 7 TBL
Bloom 6TBL
Bone 4 TBL
Cal-Mag 3TBL
Molasses 4TBL
Meta-K 2TBL

Final PH is 6.2-6.3 and PPM's right now 1,004.



Advice would help. Thanks in advanced.

you got organic fertilizers

I don't know what its derived from or how long before it becomes available to the plant

I really cant confirm this but I could guess you might be under fertilized all around ...
I see some purple on the leaves plus the yellowing

could be N def, Mg def , and possibly lacking in P

id add some Epsom salt 2 tsp per gallon a couple times then cut back to 1/4 tsp per gallon with each fertilizer feed

not sure how you should remedy it with the organics vs response time and I don't know much about your brand

I might consider switching to the GH floranova 1 part fertilizer to rap them up... its not organic but itll provide soluble food asap

or maybe ask around in the organics section where the organic guru crowd hang

they might suggest pumping in some teas and maybe some guano (both high P and high N) might work and is quickly available, but theres organic gurus here that can give you better organic advise than me

Thanks for your response. I'll try some Epsom salt and see what others have to say.
