L3Vi Posted January 13, 2022 Share Posted January 13, 2022 I have 4 plants that are grown in 30% coco, 30% perlite, 30% compost, 10% wormcastings and some amendment like bone meal, rock dust, atlantic mix of kelp and other amendments. They started out with small dots and i thought it was some small heat stress as we have had some hot days. But i then discovered white flies and winged fungus gnats. I went out and got a organic pesticide and sprayed it on. The white flies were gone and the plants looked healthy but today they are looking much worse. I don't know if it is a bacteria, a insect or under/over nutrient. I did give some vermi tea at the end of last week. I give my plants rain water that i save in a big 500 litre tank. I ensure my pH is 6 to 6.5 range. They are small and in an average of 15 litre pots. I am watering about 250ml of water each morning as the heat is drying them out fast and i do not want to run risk of overwatering. Any help or advice will be much apreciated. Note: 4 different strains from white widow to durban poison. 1 Quote Link to comment Share on other sites More sharing options...

Bos Posted January 13, 2022 Share Posted January 13, 2022 Those white dots are a sure sign of spidermite damage and won't "heal". Check the underside of the leaves to confirm. An organic insecticide should do the trick, just be aware that spidermite are persistant buggers and can develop resistance to insecticides. A topdress with mulch/straw/grass clippings would help with evaporation. The new growth looks good and healthy, which is a good sign. 3 1 Quote Link to comment Share on other sites More sharing options...

Ill_Evan Posted January 13, 2022 Share Posted January 13, 2022 I would give those plants a douse of Efekto Eco Insect Control and remove the most affected bottom leaves. I've tried white knuckling through thrips and it just didn't end up well. I now treat all my veg plants once they are mature with a douse of Efekto to keep the common pests away. 2 2 Quote Link to comment Share on other sites More sharing options...

I second this - i had a thrips issue last night - i sprayed the Efecto insect control, and today i no longer have a thrips issue 2 1 Quote Link to comment Share on other sites More sharing options...
L3Vi Posted January 13, 2022 Author Share Posted January 13, 2022 Thank you to all who replied. I will keep a close eye on the plants and baby them for the next few days. Also will go out and get fungicide as a preventative. I have 3 plants doing amazing and this is my first run into trouble will add a photo of my girl. 1 Quote Link to comment Share on other sites More sharing options...

Ill_Evan Posted January 13, 2022 Share Posted January 13, 2022 I know thrips and such usually will go for the weakest of the plants first, or rather that's what happens in my experience. I could have a totally healthy plant but the one right next to it is another strain and chowed by thrips. Could also be wacky coincidence.

West Coast Vaper Posted January 13, 2022 Share Posted January 13, 2022 What I tend to do with my outdoors is give the plants a fairly good mist spray with the hose pipe once the plant is strong enough.A good spray under the leaves really disturb any of the pests plans.My main problem tends to be those miner things (forget correct name now) at the moment.Sent from my S40 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

Will leave a dried hole in leaf but at least no miner 1 Quote Link to comment Share on other sites More sharing options...
