plants are at 4 weeks flower
Just notices today the top leaves are getting a brown colour on them. Just curious if it is strain related. Currently not on all of them

Thanks

Usually when no on responds it is because there is not enough info and there 1st question has to be to ask for more info, and there is no shortage of newbies that say "Can't you just tell me from the picture?" which is an immediate turn off to any educated growers trying to help.

The brown is not a strain characteristic, something is going on. It is early so even as it continues you have plenty of time to fix it. You will only get guesses with out more info.

This is a paste, the questions are not specific to your situation.
The more information you give the better the help you will get.
How large are your pots?
What medium?
How often do you water and how much water do you use when watering?
What nutrients?
How often were nutes used between just using water, how much of each nutrient was used?
What temps and humidity?
Do you have fans for air circulation?
Stuff like that and other info will help.

Nutrient BURN.

Too much, dial it back 30%. Burnt tips and curling would be your first sign, but you ignored it and continued so now burning in-between veins is going on.

Thanks for responses. I think Hex is right. the previous week i was advised by hydro shop guy to up the EC ( was really low (.5)
which I did slowly bumped up to 1.5 over a week. I asked them about the curling of the leaves and they said it was heat. (i thought it was too much nutes)
How large are your pots? SMALL (9 plants in 10L container)
What medium? (Clay balls)
How often do you water and how much water do you use when watering? EB AND FLOW 15Mins on 15Mins off while lights on
What nutrients? Canna Aqua Flores + Cool Bloom GH
How often were nutes used between just using water, how much of each nutrient was used? EC Currently @1.5 with half canna half GH
What temps and humidity? 25-30C 30-60% water temp constant 20C (chiller)
Do you have fans for air circulation? Exhaust and evap cooler intake
