So i thought i had nute burn but today i was looking to see if my flush had worked and to my dismay i have found tiny all white spider mites crawling on all the plants i just started to flower and on the ones in the veg room........... RUI what is the first line of defense please help.

Cool thanks grob, i figured it was something to do with maximizing yield or basically just because indoors you can control that factor. i wonder how big of a light leak it takes to produce light equal to moonlight.. i had a crack on the zipper of my grow tent that i didn't notice right away so...

What is the difference between moonlight and having a small crack in your indoor grow room that lets a small amount of light in... Plants growing outdoors don't mind the moonlight why should indoor plants have to be 100% dark.... just high and thought RIU could solve this one for me..

Can someone please help me here...

look at the root coming out of the bottom of the starter pellet... When do i need to transplant to pots?

Ok so i am starting my next grow and have seeded four nirvana pure power plant and five nirvana wonder woman. They have been good so far but a few of them have their main root already sprouting out from the starter pellet. i am scared that the light will cause the root to die... Basically i'm...

So ya i am growing in fox farm soil with fox farm grow big nutes. these plants have been veggin for a month and a half just about to move to flower room.. only two of the seven are showing these signs all the rest are ok. going to flush and see if that stops the negative signs. thanks RIU

So ya, what is wrong with my plants?

ha thats what i was thinkin about doing.. i think i might try 3'x4' scrog. I have nine, two and a half foot veggin plants right now tho... not sure where to fit em all in.... at first i was gonna do sog but scrog seems more fun and higher yielding.

ya thats what i figured.. it just doesn't seem like 400 can go the full 4x4 if your not tryin to screw the outer plants... thanks

it just seems like i see alot of ppl using 600 or even 1000 for a 4x4 foot area.. can my 400 wat hps really cover the 4x4 and still have good growth?

Honestly thank you it sounds like i'm having the same problem.. i'm using ocean forest soil and fox farm nutes but there pretty big plants for only 3 gallon grow bags that may have affected it.. It seems like there still growing but there is definitely a major loss of leaves. ya i'm gonna...

Yo i need someone to clear this up for me ha... i really don't get it

Ok i'm pretty sure its not spider mites at this point.. I'm about four weeks into flower. i have 20/20 vision and can't see any signs of them web/eggs/movement, also my humidity is very low so i dont think its mold/mildew.. i'm upping some slightly better photos but there under hps light so...

nothing on underside of leaves.. at first it seemed like it was something like water spots or from spraying on nutes but i never did that so idk.. i havnt looked into powdery mildew but i will.

I cant find any other signs of infestation other than the leaves looking like this, i originally thought it was over fert but i flushed and its still gettin worse and its on all of my plants in flower room. really startin to scare me. Also sorry about shitty pics its cell phone camera...

right but its still emitting light at a certain degree. It just seems weird that grow manuals ect always make such a big deal about total darkness i'm just wondering if it would do anything by allowing a little crack of light. Basically for example my tarp zipper for my grow tent lets in the...

When you grow outdoor ganja the nights would never be truly pitch black like it is in the nights in a grow room because of moonlight... just wondering how much light the moon projects and if there were small cracks in the grow room would it not really affect the outcome. is the moonlight a type...

ya it was only one night and i'm just about four weeks into flowering.. I was just wondering if it would affect yield or flower time

So i have one room that i'm growing but its split into two seperate rooms one flower one veg for perpetual harvest... so my roomate left the wall seperating them open so the plants saw one night of 18 hours instead of the normal 12.. it wasn't direct light but light nonetheless. I was wondering...
