HELP! Help with flowering plant

[JayDubya]

5 gallon pot
Strain - Badazz cookies og
Nutes - Combination of reefertilizer, big buds, bud candy.
Micronutrients - Marphyl phytoplankton.

On week 3 of flower.... Last watered with nutrients 2 days ago. I've noticed it has been shedding lower leafs, kinda crumpling. Some fall off, some come off really easily when touched. Now the top leaf in the picture is discolored. Any advice appreciated.

How close are your lights? Looks light light burn.

[JayDubya]

JayDubya what is your ppm or ec?

[JayDubya]

Hey! I know ppm stands for parts per million I am just unsure what parts are we talking? Sorry, very new... do you mean the numbers and ingredients on the nutrients?

[VN1970]

Hey JayDubya
It’s the total nutrient level in your water; nitrogen potassium calcium phosphorus etc. Get a ppm pen on Amazon and check your water daily along with ph testing. GH flora trio has a recommended ppm range for various stages of plant development. I try to go a little lower to prevent nute burn.

Oh yeah
since you are growing in soil you’ll need to check your runoff as well as the water going into the plants.
Good luck with your grow ☮️

I use the SF lights. 15 inches is to close for that light. Learned through trial & error. Burns leaves like you have. It will stress out the buds and plant. recommend raise it to 20 inches for a while. I try not to let it get closer than 18. Also if u have the external dimmer, turn it down to 60% or so for a few days. It looks like you may have some nutrient issues also but I am not a soil grower.
