Leaves curling and tips turning brown

Hertronix · Oct 10, 2024

My plant is in week 2 of flower since q week or so she has stopped growing.
And the leaves started to hang down almost like overwatering, but I didn't over water. Then the tips of the leaves started turning brown. From bottom to top ( but some leaves even in the top part of the plant ). Now 2 days ago the leaves wich have brown tips started to turn yellow. And the top leaves are curling down.

It looks over-watered and very overfed. How much and how often have you been watering and feeding? What media are you growing in? How big are your pots? What light are you running? How close to the tops, and at what dimmer setting?

I water every 3 days when the top 2 inches of the soil are dry. I haven't been feeding since about 1month as I started seeing really light nute burn. I have just a standard soil mix nothing special. My light is the spider farmer sf1000d its set at about 40cm above the very top branch. My pot is like 24 liters to 28 iam not sure
Iam guessing it could be nutrient lockout do to overfeeding. So I'll prop flush, but iam scared it will not life the flush.

There are lots of ways to grow, but I find that the finger test in the top of the soil is a lousy way to gauge moisture content. I go by weight.

You could feed with regular water until water comes out the bottom, then check the PH from the water that drained out of the pot. At least you will have some useful info to help diagnose the problem. Good luck

I'd want to know the runoff EC before thinking about flushing.

Checking runoff water could possibly rule out nutrient lockout. When I grew my first crop I used power si without adjusting PH and ended up with nutrient lockout. I was told to check runoff and was able to diagnose and treat ph issue. I do not know the nutrients you are using so I am just guessing.

Medium?
Pot size/type?
Nutes?
Feeding schedule?

This is what I started doing I felt my ppot when I filled them with dry medium I bet I lifted these mfs 1000 time just to get the feeling of "dry" soil

Thank you I will do that.

I also think weighing is a lot better option. My 1 gallon pots nearly to the top with soil when moist weigh a lil’ over 3 lbs. I’m still waiting to see what their weight is when dry. Can anyone tell us about what the weight should be before watering agsin?
