IF YOU WANT A BETTER DIAGNOSIS LOOK HERE FIRST

[GanjaRobPDX]

There is some basic information that really helps diagnose plant problems.

1) Are your plants in veg or flower?
*how many weeks in veg/flower?

2) What type of system?
*what type of grow medium?

3) How large are your plants?
*when did you last re-pot?
*what size containers

4) Light wattage (400,600,1000)?

5) What type of nutrients?
strength of last feed(ppm)

6) What is your pH?
*soil pH
*nutrient pH

7) Average temperature/humidity?

8) Strain and Sativa/indica ratio

If you dont know some of these variables, thats ok. the more you can provide, the easier it will be to diagnose plant problems. Pictures of the effected area are always very helpful in addition to the above info.

1)veg or flower
Whether or not your plants are in veg or flower gives others a better understanding of what plants are going through as it relates to nutrients and growth.Tthis also helps with problem solving, as there are many treatments that can not be used in flower. Many treatments need to be adjusted during flowering to avoid damaging flowering sites or effecting taste of the finished bud.

2)Type of system
Mentioning the type of grow medium you use is very important.
in addition, the type of system you use is critical for recieving the best advice possible.
many variables are drasticly altered simply by switching your grow system.
For example: Advice given to one grower who is using a coco coir medium could be very different from someone else growing in a deep water culture system.

3) Plant size
This is mostly for determining nutrient strength. Time between repotting is helpful in determining whether plants are root bound and need to be transplanted.

4) Light wattage
No one needs to know how many lights you have. However, light wattage is extremely helpful in dialing in nutrient strengths. Since light energy greatly effects the plants use of nutrients, it isnt safe for someone using a 1000w light to offer their same feeding plan to someone using a 400w light. food for thought.

5) type of nutrients.
This is a two part question really. Organic or chemical is the big one.
As many of you know, organic nutrients often have a poor EC/ppm reading and consistent readings from one meter to another can vary greatly. So, a 500ppm reading on my meter using organic nutrients can read anywhere from 350ppm to 600ppm on your meter, respectively.
The second part of this is to mention the brand of nutrients you are using. It's easy to go online and look at a products NPK levels. Combine this info with a basic idea of your last feeding, along with the other variables mentioned, will really cut down on the time and guessing that goes into diagnosing a plant problem. Everything is symbiotic and ties together in very important ways.

6) pH
Soil pH is very important. It tells us what the soils actual pH level is.
You can do this by pouring water through your medium and testing your run-off water.
Nutrient pH is very important as well.
If your pH is off, it will greatly effect your plants growth and nutrient up-take.
Leaf twisting, especially on newer foliage, is a common sign of pH being off.
If you dont have a pH meter, get one. These damn things are as important as your lights.

7) Temp/Humidity?
Temperature and humidity are extremely important to nutrient diagnosis and prevention of mold and mildew issues.
Temperature and humidity also effect nutrient uptake in a big way. Major fluctuations of either one or both can cause major difficulty in dialling in nutrition needs for a given strain.

8) What strain? Indica/sativa Ratio?
Strain is helpful, indica/sativa ratio is even better.
Nutrient strengths for sativas is far different from indicas. many equatorial strains have different sensetivity to light cycle adjustments.
Sativas are almost always harder to grow and require more attention to detail throughout the cultivation process.

I hope this post can be used as a template for people posting with plant problems.

I hope this helps.

Thanks so much, that took a lot of organized thinking to put together, seems like if I really think about the answer to YOUR questions about my grow, I stand a good chance at answers for MY questions about my grow. Clearly those answers can be a lot more specific to the situation when you have more information.
I am printing this one out, thanks again.

no worries, just making my job easier. There are a lot of people who want to help on here, but they need the right info to provide a solid answer.

First one is for soil. The second one is for hydro.
