Hello 420,
Its been an interesting week in the garden for good and bad. Lets start with the good.
Flowers have been developing nicely. Scents are not over powering but man they smell good. The Love Potion is my favorite with its lovely berry scent. Its getting sticky in there as well. It doesn't look like Ill be harvesting a lot of weight but having 3 different strains will be nice.
The bad news is Powdery Mildew. I first notices it in my veg area, I don't have a proper air exchange in there and it caught up to me. It showed up just after the last water. The plants are getting bigger and they all got watered the same day and humidity spiked. According to my cheap digital temp/humidity monitor ($4.99) my humidity never got higher then 52% but that's inaccurate. It felt like Cuba in there so I put all 4 cheapos and my indoor/outdoor in there to compare. Temps were consistent across the board but humidity varied by about 20%.
Tuesday-Removed infected plant and culled it. Didn't change anything else
Wednesday-More plants affected, Started leaving the door to the room open. Dropped humidity down to about 35-40%. Lowered light closer to the canopy and turned up the heat to make up for the loss of heat do to door being open.
Thursday-Culled more clones, almost half. Wanted to give them more space and avoid any future spikes in humidity. Sprayed a baking soda solution.
Friday- Not seeing anymore spread of PM and whats there doesn't look nearly as bad as it did earlier in the week. Humidity seems to be staying in the 40-50% (could go as low as 35-40% if needed) Some leaves have turned brown form the damage earlier on.
Saturday-Powdery Mildew in the flower tent. Discovered this last night. Will add another fan today and turned up the exhaust fan. Also sprayed Baking Soda mix in there last night (Baking soda, veg oil, soap,water) I figure the spores were on my cloths and were transferred.
Today- No change in veg room but sprayed baking soda solution at lights on. Will check on tent in 5-6 hours
Tuesday
Saturday
I'm looking for any comments or suggestions on how im trying to control this or what you have done in the past that has worked. I'm only 2-3 weeks out(maybe sooner) so don't want to lose the crop but also no point in smoking anything that's going to affect me negatively. I was originally going to go with a sulfur spray but read that the residue left on the leaves and flowers make it unhealthy for smoking/eating.
Would you recommend removing any infected leaves and if so the entire leaf or just infected areas?
Cheers
*I really didn't expect the practice clones to make it flower. Just kept them around to see how long it would take for them to get root bound in those pots and to mess around with
**Was planing on transplanting when I harvest in 7-17 days aprox into 15gal but could move them into a 3gal earlier if needed
Cheers
They look rootbound to me.
That isn' PM.
Could it be left over foliars on the plant leaves once they liquid has evaporated? That could also explain the burnt leaves since the stuff is acidic. How heavily do you spray them and what concentrations are you using (sorry - I'm new to your journal).
