These leave are from a five week old Northern lights auto. I was hoping any plant Dr’s on here may help. Thanks in advance if you did.

I’m terrible at diagnosing but this chart might help you
Tagging some others to your thread would help as well

Northern lights rqs auto
Coco 70 perlite 30
30l plastic pot half filled 2/3
5.8-6.2
Canna range full
600 ppm
Run off a bit higher 750
Indoor
18 off
28 on
50 rh
8x4 foot
2x 600 hps
Hope this helps
600 ppm seems pretty low forba flowering plant? Why did you use that light schedule?
What is your EXACT pH from either run-off or a slurry test?
Also, lights on 28 hours, then off for 18? You’re ensuring your plants are getting a proper DLI?
Yeah… it looks like the tops spit out one finger leaves, so I’m guessing that light schedule has them confused

This far into flower i give my autos between 8 and 1200 ppm intake. U are going like half the amount u can run. Try to get a bit more nutes to her and see if she picks up. Might be starving for food. Id also soak it down til i get good runoff with the new nute mix. It dont look horrible but def gonna have some smaller bids than it should be. In coco i stary full strength nutes from the start and run it the whole time. Not always a nute drink somedays is just ro water and some calmag. Good luck my friend.
@Mark0427 the ppms have all gone up since I watered less often. I have had Co flicting advice. Some say wet dry wet and others say water from 1 to 6 times a day. It’s my first grow alone and I’ve made the mistake of running 10 different strains at different ages. All autos. Just to learn on really. I’m trying to clone and maybe at 20% survival. I’ve just received a white gold female from sensi /white label. I want to get it nailed down before I germ that bad boy. It was their most expensive so I’m expecting good and hopefully will have have nailed cloning too but that’s way off.
Another q. I got given a booster that is 0-50-30
Does anyone know about this. It looks abnormally strong but I am new and I wold like to use it

I use flower fuel as a booster also it has high numbers. Its made for flower to help boost the stuff needed during flower time. Give it a run with your nute mix. If it calls for a tsp per gal try half or quarter that amoint to start with autos. If u do 5 gallons and it says 1 tsp per gal try like 2 tsp per 5 gals and see what that brings. If no tip burning after 2 or 3 days next feed bump it up to 3 tsp per 5 gals til u hit 5 per 5 gallons. The boosters do help alot i have noticed with this last harvest i did
