How to Use Plant Dr as a preventative fungacide

I see this was months ago. Please select me as the answer so I have a chance to win grower of the month contest, I would truly appreciate it growmie!

Anyone other opinions on the product? I'm growing outdoors in soil and I have no symptoms of a fungal infection I was just curious about using it preventatively as I live in Central Maine where humidity gets very high and Temps fluctuate greatly. However I grew clones before and I have an idea they may have been infected from the start.

once infected, you should remove more than just the leaf with a spot. i'd take off more around it too. the larger the spot, the more you amputate. Here's the thing to remmber. A good chunk of this organism exists inside the plant. just because it gets cleaned off on the surface does not mean you have rid the plant of fungus. always better to amutate, apply some foliar spray and pray. Avoiding the infection is key. standing water on leaves is bad. high humidity is bad. extremely low humidity is bad. plant health is key. A weak plant is more susceptible to disease than a healthy one. That is just phosphoric acid, if not too fuzzy to read. I don't know if it fits through the stomata, but if it does it is something you'll need to consider when using that product. Too much P causes the same problems whether it comes from roots or elsewhere. Deinitely do some testing first. A good horticulural oil in vegetative phase is a reventative measure you can take. it will not kill fungi, but it makes it much harder for it to starta colony while coating a plant. NEem oil is an option, but i'd go with clarified neem oil for this use. You dont need "azardirechtin" or wahtver it is called - that's the chemical in it that is somewhat dangerous. without it, it's basically just horticultural oil with a bad smell, lol. isolation is a good idea while you treat a plant. Otherwise it will just spread more. If it keep popping up, kil the plant. even heavy-duty antifungals are not very effective and do not kill off an infection. it only reduces impact. And, those are the chemicals you can't just buy at your local HD or lowes. if it is consisent, consider a diet change. I found bumping P from my normal formula improved resistance. i had wpm on several consecutive grows. Finally had a couple clean grows lately and i think it was in big part to not being short on P, despite no outward symptoms of low-p

Also, if you need a fungicide for newborns., sprinkling a pinch of cinnamon around the babies and watering in, is all that's needed. Very cheap

By keeping your ph, ec humidity and temperatures in control at all times., no plant doctor jug is needed. By checking and keeping the elements in the proper range, makes you the doctore. The only doctor they ever need. If you don't keep all these elements in control, plant doctor jug won't help you much.. cheers and happy growing..
