I have read allot of post and tried to figure out what is going on with this .I'm not sure if its fungi or a deficiency? I know its a redundet question. I will say the humidifier sprays directly toward the plant that shows this..I was thinking it had something to do with the water vapor, any thoughts?
Ff soil, ff nuts,400w mh light temps on the high side 74-86, rh 25-35% watering ever three days, alternating food with pH water. All my water is run threw a filter and the pH to 6.3.

Looks like heat stress to me. You wanna typically keep your temps in between 70° and 80°. 85°+ might burn your plant.

As far as that discoloration I see, I'm not sure yet. Let me look into it for you.

Good day good people!

I've been baffled by little spots on some of my leaves, especially the lower leaves. Closest I seem to get is Calcium deficiency.Would anyone mind having a stab at it?

More info:
-It is slightly warmer in the grow room that ideal (don't have a temp guage but would estimate at 27 degrees celsius)
-I live near the coast so moisture levels are routinely above 80%, I do however use a dehumidifier a few times a week to lower moisture fro a few days
-Spots are mostly on lower leaves
-Most of the leaves show no damage and plants looks healthy. They are in flower now and growing good sized buds.

Help would be appreciated, thanks.

Dealing with snails, slugs etc. ... easiest method is to save your egg shells, crumble them around the plant base to keep these two away, ... lava rock etc. works as the rough surface keeps them away.

just a quick update forgot to take pictures and tell yous how the grow went all went well in the end nice smoke and alot of thc but i wouldnt recomend growing with household lights as it takes far too long and not a good yield was my 1st grow and had got told of many it would work just the same as cfls bullshit. i ended up with 7 plants and only got 2 and a half oz in total and went on to get a 400w hps and have been pulling off in between 3-5oz a plant so i would recommend decent nutrients and proper lighting it might be a wee bit pricy but the end product is well worth it. I just thought i would share my experience and help any body that might have had the crazy idea to try it lol. Stay medicated my fellow stoners

 

[katurango]

Can anyone ID these critters? Found on only one leaf, but on both sides of the leaf. TIA, katurango

I know this is off.the topic a little. I took a break this summer from growing, due to an awesome harvest. I had spider mites. What the best bomb for the room and tent.. I plan on scrubbing down the everything I can with bleach. Thanks guys u helped me so much

 

[IceMagnets]

Hi guys. This is my girl in 4th week of flow, but we have some problems and i need ur help..

What should i do??

 

[Suntana]

That's not a serious problem man, it's not uncommon for leaves to die off on the bottom, later on in flower. They look good no worries

 

[Grow Bro]

Can anyone say what up with this??

Is it nutrient burn??

 

[Dave Groomer]

Indoor? Outdoor? Soil? Hydro? Nutes? Lights? Way too many variables without more info. Pics of the whole plant would help.

 

[DonChiefums20]

Are these spider mites?
