there have been fungus gnats in the room. i put some hotshot pest strips and there gone now.

This is the only female out of a cheap mixed bag from nirvana i bought for some practice runs in my new box. i decided to go 12/12 from seed with the last 3 seeds. and this is where I'm at now. My flower box is 3'wX4'hX 20''D. 150hps air cooled
its being vented with a dayton 134 cfm blower pushing into a can filter mounted outside the box. its intake is 2- 2' PVC pipe coming in passively from the mother room that has 3- 2in pvc pipe passive intakes.

I noticed this spotting a few days ago. i thot it was light bleach as i had the plant about 4 inches from the light. I droped it down to about 8 inches above the tops. I also noticed roots are coming out the holes in the bottom of the pot.
anyways here are some pics. pls school me.











Mahalos!

Put the plants up on a counter close to a light and look closely at the leaves and stems of your plant(s). Make sure you don't see any webs or tiny insects/spiders. Some can be difficult to see.

After verifying it's not an infestation -
I'd back off the subculture and the fertilizers for a week, see if it spreads or gets better. Then the answer will be clear.
Subculture isn't something you should have to use more than a couple of times. They want you to use it up so you buy more. They also tell you to use way more than you need at a time on the label. Typical

Different plant

Different plant

Stitch,
this is a different plant than the other one,,,,this one is a flower box and being fed differently.

 

[pufpufgiv]

this seems to be a different problem also as I dont see the real heavy red dots here...you tell me...I have no idea.

Is this the same problem as my other plant......using the same soil...prolly is

 

[MynameStitch]

Ahh I see, my bad......
so the information I posted in the other thread was portaining to this plant then not the other plant?

So is this the one you were feeding every 3-4 days?

 

[pufpufgiv]

OK stitch I'm sorry for the confusion....but these are two different plants at different stages.. w/ differnt feeding schedules...HOWEVER....they both have the same soil. does the spotting look the same to you??? this plant does not show the heavy red dotting that the thunder**** clone in other thread shows.
This plant in this thread is taking nutes every 3-4 days.

THey are a little burned imo; how long were they in the mixture before you started to feed them?
Your growing different strains right? All different strains can take different amount of abuse... some can take more than others some are very touchy like some of your other plants you have.

I would flush her out and feed her every 7 days, once a week; The amount you are using for every 3 to 4 days is high and your plants got a buildup; flush this plant out, but not for 3 to 4 days; flush her with about 4 gallons of water and wait a week before feeding; when you do feed give her a light dose and the cal mag, do not use over 3 ml per gallon of water for now; your dose is very high as it is....

Why are you using 2 different bloom NPK feeds...... imo that is too much; pick one or the other... the floriclious is the bloom one your using right?

WHat nutrient is subculture?

When you use a high amount of cal mag; it's like your giving them hard water and it makes it hard for them to absorb nutrients right..... so do not give them high amounts of cal mag
