By posting in Southern Cali you have limited yourself to replies from people who actually read that section... which is only a small percentage of members. I've moved it to problems where it belongs. If you check IC, HeadyPete and MyNameStitch are going to be your best bets for troubleshooting. They are both quite intuitive and experienced. This site can sometimes take a bit longer, since there are fewer of us, but the quality of advice is IMVHO actually more consistent here. You are less likely to get misleading or simply wrong answers from noobs- those get deleted if they are totally off the wall, lol!

Yes, Serenade makes an effective soil drench. It is not technically a systemic, as it is a live bacterial culture and cannot be taken up into the roots, but inoculating the soil is never a bad call. If you have grey mold, other rots are likely since they thrive in a warm, humid environment.
You need a dehimidifier in your grow space; if outdoors, you need a breezy location and a mold-resistant strain bred for humid climates. Try Federation's Sweet Island Skunk also known as Island Sweet Skunk or ISS. It should be available at dispensaries in clone form too.

Now for why your plants are so sick. You say salty water? Ding!!! Nute lockout leads to poor health and necrosis, which is then vulnerable to disease. Mold will affect unhealthy or dead tissue first.

It also sounds like your organics regime needs some consistency. Start with your water. If it is salty, you can't use it. Even with leaching, that is going to cause problems. Plus every 3 weeks is too infrequent if you know your water is problematic. Try adding a chelator to your nutes; the Canna Bio has a high level of organic acids which will aid in flushing out unwanted salts, and it is organic. I would approach it by letting the pots get fairly dry, then giving a watering so heavy as to force liquid out the drain holes, EVERY TIME. And find a better water source.

MG Organic Choice is okay if you add ~30% perlite to it and treat it like a soilless mix similar to promix, but with much more fertilizer in it. Somewhere between promix and ocean forest. Read the why should I re-pot thread in the FAQs. Composted humus with perlite is also good, and in your case, I think that the naturally occurring humic acids will be beneficial to your overall situation.

Can you post up pics and fill out the troubleshooting form so we have all your info? Such as, how high is the ppm of your source water? How and at what point do you check and adjust the pH?
stinkyattic Reviewed by stinkyattic on . Boytritus is still spreading:( Hi guys, I posted this as a Reply to my original post (in newbie plant problems), but didnt get any activity on it and was not sure if the forum would alert anyone I had responded or if I needed to do a new post. Please forgive the repetition of info as I learn to use your forums Heres the new problem, or the continuing old problem... I think it is boytritus. It forms at the branch node - grey and fuzzy and goes INTO the stem - bruises the stem until it is so weak it must be removed. My Rating: 5
