PLEASE HELP..... LEAVE DISCOLORATION

[atrain17]

WHOOPS....... Meant to say "LEAF" discoloration

So here's the story..... my plants I believe are sick. Some leaves are two different shades of green. Some have brown spots and streaks. I posted pictures, sorry they aren't better. I can try to get better ones.

This is my first time growing in soil so I'm not too familiar with it. I used miracle grow, slow release fertilizer soil in 5 gallon bag pots. I believe the NPK are all pretty normal as I tested them with a soil tester kit and the colors looked right. Also, the ph is around 6.0. Temp is mid 70's and humidity has been around 90% since I sprayed, which leads me to my next point......

I had mites not too long ago so I sprayed a couple of times and they seem to be gone. Could this be causing this leaf discoloration?

I'm running a 1000w in a 5x5 grow room. The light is about 2 feet from the tops.

Thanks in advance for all the help.

Wassup Atrain?

What did you spray with?

PH 6 is too low for soil. You wanna shoot for 6.5-7ish. Is it actually soil or is it soilless?

Slow release fertilizers cause problems as a general rule.

I keep my RH around 50% for veg and 40 for flower.

Got a picture of the whole plant?

Check out the sick plant guide, fill out the questionnaire and post it up.

Whad up Georgesmiley!

Thanks for the help bro..... I'll get that questionaire filled out as soon as possible. In the meantime, I'll answer the questions ya asked me though.

First, i'll try to get that PH up and humidity down.... thanks for that. It is actual soil, yes. I'll try to get pics of the whole plant.

Thanks for the help..... I wanna get these little guys better soon.

 

[atrain17]

Also, I sprayed with stuff the guy recommended at the hydro store. it's called AzaMax. Active ingredient is Azadirachtin 1.2%. Also bombed with Dr. Doom.

Thanks again.

Well the azamax isn't going to really hurt things from my experience using it. Haven't used the Dr. Doom though.

The obvious things here are the miricle grow. You mixed 2/3 ferted miricle grow soil or miricle grow fertilizer with the peat? That sounds almost like a soiless mixture.

So your choice of soil is a complete "unknown" for me since no one really sports the MG stuff I don't have a lot of knowledge there. Have you tested the PH of the water before you water and the PH of the runoff? I've never had luck with a soil PH test.

But what I do know is your environmental's are fucked

Your humidity is way too high, and your temps are too high with lights on and too low with lights off.

My rule of thumb is nothing below 72 lights off and 80 lights on (canopy temps) Now it can be a bit hotter and a bit colder but it Cannot swing that wide. With cold temps the plant is going to stop taking up P and the stems will start to purple up and look like lockout.

Thats just my first glance.

Awesome..... I'll try to get my temp more average then. I thought I'd try soil this time but obviously I need to go back to hydro where I'm more familiar. I'll go buy some pH increaser and get a ph soil tester. I'll fiddle with those temps a bit so they stay in that range. Humidity should go down a bit now that I'm not spraying AzaMax. I'll work on that, thanks.

I thought maybe it was because I was using tap water. I let it sit plenty long but there still could be stuff in there that it doesn't like. I'm going to start using better water and fiddle with those temps, humidity, and pH.

Any other helpful tips or anyone know what's causing this? Only some of my plants look like this...... some are fine.
