Possibly a pest problem?

[trueg115]

A few of my leaves on my plants are starting to get brown/black dots on them and the yellowing/brown around the edge.

I thought this was due to PH, and resolved that, but it is still continuing to get worse. I have searched for possible nute deficiencies but can't find one that matches what my leaves look like. Could it be a pest?

Lights- 150 watts of MH and 150 watts of CFL
Bubbleponic Nutes a day 20 of veg

Thanks in advance

Looks like something fungal. Or mold. Make sure the air is moving in there...add a fan if you didn't. Diluted bleach in a spray bottle sprayed on the soil surface should kill anything on the soil surface.

A little baking added to plaiun water and sprayed on the leaves MAY help get rid of it on the foliage....Or keep it from spreading.

I'll try the baking soda and plain water

any other suggestions?

I'd do both. It could be on your soil surface too. Taking care of the leaves and ignoring the soil wont take care of it. Do both or do neither and just leave it to survival of the fittest.

Well its hydro, so unless they can somehow get into the water I dont see anything I can do about that? besides spraying the outside/inside of the resevoir

What kinda medium are you using? Rockwool/Grow Rocks or something else?

i gots a pest problem too..hornets love to sleep on my leaves..i dont kno why but everytime i look at my plants theres a hornet of one of them

 

[trueg115]

I'm using rockwool and hydroton

Water and 5% bleach. If you can remove your rockool/plant...Remove the plant...drench the rockwool cube with the diluted bleach/water. Dump your res and clean it thoroughly with the same kind of water/bleach mix. Refill res....put the plants back in. Done.

hornets are good! send me some

 

[NLights420]

really hornets are good..r u sure..they dont eat the plant they just sleep on it..maybe its the sweet smell

I took some baking soda and sprayed all the leaves, then left the fan on them to dry the up quicker. Well when I went to look at them today they all had a huge growth spurt overnight. and the diameter is almost twice of what they used to be. I also notice all this white stuff on the leaves. Could this be the fungus or something that was in them? Or possible its just little pieces of baking soda that didnt evaporate?

Spray the leaves with plain water to wash off residual backing soda. Its more than likely the baking soda.

Good luck.

Thanks BSI for your help. The plants have flourished since I started spraying the baking soda.

It isnt harmful to spray the baking soda/ plain water on every other day right?

As long as you rinse them off with clean water after it dries...You should be fine. But too much of a good thing applies with everything.

If you see a new outbreak...hit em again. Other than that I'd let them do their thing.
