Guide for Diagnosing Plant Problems

I was just looking at the FoxFarm schedule and i do see that they have you add grow big throughout bloom.
A problem that most companies do is have growers add an excess of N/P/K like all together during the same phase of plant growth. What i mean is that the plant needs certain amounts of elements at different stages of plant development.

I do believe they got too much nitrogen atleast during one period and honestly the grow big might have been the reason.

I could go into further detail about this but Aptus paints the picture much nicer than i can with a blob of text on a forum.
check out this page all about "tomatoe" plant education

I am not trying to push you onto other nutrients, i just want you to better understand what each of our precious ladies need and exactly when they need it so that they stay nice, healthy, and produce strong yields. =]

Hey I'm going to throw up a pic tomorrow when I can get one. My white widow , cookie kush, and deep cheese are getting white spots on their leaves. Not like fuzzy spots for that mold. Thus it could be that. I did the baking soda/water trick on the leaves and it didn't seem to work. Anyone got any ideaa?
 
I came across this neat little list that can probably help a lot of people out. If you like it check my post in the General area...I need some help!

Quick Deficiency Guide

Nitrogen: Entire plant is light green in color; lower leaves are yellow; growth is stunted....

Phosphorous: Entire plant is bluish-green, often developing a red or purpleish cast; lower leaves may be yellow, drying to a greenish-brown to black color; growth may be stunted...

Potassium: Leaves have a papery appearance; dead areas along the edges of leaves; growth is stunted...

Magnesium: Lower leaves turn yellow along the tips and margin and between the veins; the lower leaves wilt...

Calcium: Young stems and new leaves die...

Zinc: Leaf tissue between the veins is lighter in color; yellowed; papery in appearance...

Iron: Leaf tissue appears yellow, while the veins remain green...

Copper: Leaf edges appear dark green or blue; leaf edges curl upward; young leaves permanently wilt...

Sulfur: Young leaves turn pale green, while the older leaves remain green; plant is stunted and spindly...

Mananese: Growth is stunted; lower leaves have a checkered pattern of yellow and green...

Molybdenum: Leaves are stunted, pale green, and malformed...

Boron: Young leaves are scorched at tips and margins...

Hello everyone out there I am new to the game and have a couple of seedling about 15 days into veg I noticed brown yellowish dots on the two bottom leaves and brown edges on a few top leaves I flushed the medium twice already have them cal mag I noticed that they have slow on their growth as well picture is from two days ago bottom leaves or more light and darker spots any tips out there would really help thanks.

When do you decide to throw plants out and start over? I feel like im almost keeping these plants alive cuz I want to see if they can be saved?
 
My stem has mold on it and everything above is still growing with little buds but leaves are more yellow and drooping, I've already washed the area with baking soda and water solution and then treated with hydrogen peroxide but it came back this is an outdoor grow so I can't decide how much water it gets should I cut below the mold to stop it ?
