Can anyone give me any suggestions I’m growing outside and have only been using banana water and coffee water and eggshell tea for its nutrients and natural spring water
 
Need pictures - close ups and whole plant 👊 🐙

What is your growing medium? Looks like you are growing in a pot, what size? Or maybe I see it wrong (base of plant is out of focus) and you are growing directly in the ground?

Are you growing a photoperiod or autoflower? This time of year, with that much progress into flowering, it could be either, so best for us to not assume when helping to diagnose issues.

Brown leaf tips curling upward is usually a sign of nutrient burn. How often are you watering them and how often are you adding the supplements you mentioned?
 
Still would help to see a few good pictures of the entire plant. Seeing the size of the plant will help. Mainly need the info on your growing medium and watering schedule.
 
  • pH Imbalance (Most Likely)
    • Coffee water can be acidic (low pH), while eggshell tea is alkaline (high pH).
    • If the pH of the root zone swings outside 6.0–7.0 (for soil), nutrients become locked out, even if they’re present.
    • This leads to tip burn and edge necrosis because the plant can’t uptake nutrients evenly.
  • Excessive Nutrient Concentration
    • Banana water + coffee + eggshell tea = potassium, calcium, and nitrogen all together.
    • If the mixture is strong, salts can build up around the roots, burning the leaf tips.
  • Environmental Stress
    • High heat or irregular watering can intensify tip burn, even at mild nutrient levels.

Ok I’ve got a video if you want and I probably feed them roughly every 4/5 days but it’s been raining a bit so it’s been a bit irregular wen I use the banana water I put half a litre of banana water and half a litre of coffe and egg shell tea the rest spring water usually 3 liters per pot there 10 litre pots
 
Where did you get that feed recipe? Have you used it before?

Tbh mate this is my first time growing mate and I’ve just read up what’s a natural way of giving them what they need without using feeds or chemicals or bloomers
 
Test your PH at least. This is a very common cause for issues in many grow mediums. Simple and easy to test and rule out for proper diagnosis.
 
I’ll have to get one did u see the video
Yeah, just watched it. Overall looks pretty good. Fading to yellow a bit quicker than normal. Leaning toward PH issue since the top of the plant looks like nutrient burn, but the bottom looks like deficiency. This usually indicates a nutrient imbalance which PH is most likely to cause.

Ok so how do I help the ph level after getting the Tester or can I help it without knowing the level

You could adjust the PH of your nutrient solution before feeding. So if the PH of your runoff is too high, you would feed with a lower PH solution. If it is too low, you feed with a higher PH solution.

Or you would add soil amendments. Once again depends on your current soil PH. As for the specific amendments, maybe someone else with more soil experience will know what should be added if PH is too high or too low.
