Late flowering problem.

[LJ farming]

Im currently at day 45 in flower and new to indoor growing but have grown outdoor successfully for several years. My plants are in ProMix HP and I am using GH flora trio and adding cool bloom and diamond nectar as well. I keep the PH between 5.9-63 and I am almost positive I do not have a pest issue. I am not sure what happened here unless my Ph pen or PPM pen are reading wrong for whatever reason. My tent definitely ran a little hotter than I would have liked because of the ambient temp outside. Max temp was 83 over the past 2 days and I know my nutrients have been almost exactly the same for the past 30 days. Yet Somehow I went from a dang near flawless first indoor grow to now hoping I harvest. This all happened in about a 4-5 day period. Here are a couple pics and any help is much appreciated!

I have ruined a couple of crops with ph pen miscalibrated. I was only calibrating to 7 and batteries were getting weak, so was way off. Test with 4 and 7, and I like using 2 pens.

Do a pour-through and get an EC reading. If the ppm is low then it lacks nutrients if it's high then it's a lockout from too much feed. The other possibility is that the water you are using is blocking the macronutrients from linking and showing up as a deficiency. Using tap water over a period of time will raise the pH in the container and lock out nutrients. .

The way the tips are deforming is interesting. I would look at the root system. I suspect mould is at play.

I will use Ph test solution to double check my pen tonight and have ordered a second pen as well.

I will also test the run off ppm as well tonight but this might not tell me much since I flushed the hell out of them last night.

FE. What is the chances of having mold in one tray or side of the tent and not the other? I have a bad feeling you could be correct but #1 I am unsure how to check this without destroying a plant and it’s root system. #2 the other side/tray in the tent does not seem to have the problem or if it does I can not see it yet. #3 if I do find that 1 side has mold what do I do? I assume get it out of there ASAP to try and save the other side but perhaps it is too late already?
lastly what would cause the mold? For the entire grow I have kept the RH at 40% which is too low according to all VPD chart recommendations. The reason I think it might be be mold is because I got bud rot in my best 2 outdoor plants this season and I think the leaves looked similar but I do not have photos of the leaves so I am not sure. The outdoor plants had massive buds and I have read that was a large part of the problem. These indoor buds are not the same strain and in my opinion are small and airy as well. So I guess I am asking if it is in fact mold what the heck am I doing wrong for the damn mold to be in my last 2 grows?

Here is the 2 plants that almost made me cry when I found the bud rot this outdoor season. Unfortunately this was harvest day and I had basically removed almost all the fan leaves and had no idea yet that I had bud rot when I took these. I actually didn’t figure it out until the buds basically would not dry properly for trimming. There was over 4 pounds on these two plants and I threw it all in my wood stove and left the door open smoked a huge joint and drifted into my own version of a Cheech and Chong movie.

Look at VPD charts.

These photos are from last night. As you can see it is spreading like the plague. It currently seems to be strain specific. 2 seem to have it really bad and 2 not at all or or very minimal.

I thought it looked like mold starting. I had 3 strains once, 2 OG's and GG4, and the GG4 was very resistant while they others were ruined.

That's why I leave all the fan leaves on a plant as long as I can, so it can transpire moisture. Taking off all the fan leaves removes thousands of stomata's the plant uses to transport water. Mold is caused by excess moisture in the plant and so one needs to cut the water at the end of the grow at least 50%. Big bud plants need to almost wilt before giving water to them, and then just a little. I have messed up a lot of pretty plants in flowering from overwatering because the plant stops taking water during flowering. If your plants have mold inside of the stems there's nothing you can do. Over watering is the # 1 cause for bud rot.

So should I cut my losses and get the plants out of the tent that are showing signs of mold if that what it in fact is? How do I confirm it’s mold? Do I need to look at the roots, stems, or buds? I know what bud rot looks like from my last outdoor grow unfortunately. But if it’s in the roots or stems I have no idea what to look for. GG4 is the strain in the tent with the biggest problem.

Also if it helps confirm or rule out mold the branches on the infected plants are soft or too limber IMO.

This is one of the largest colas from the GG4 plants. What a waste of electricity.

My desire to see the roots, stems from how the leaf tips distorted after death. I see similar signs often, when a leaf stem is attacked within a bud, cutting off the leafs supplies. It not only dies, but curls up in this manner. Almost folding back. I have seen images of leaves scrunching up on various plant species due to mold. I know with absolute certainly that I will see a leaf go bad and fold this way, caused my decay within the bud it's growing from, before my crop is done. It's what tells me the crops coming down. For me, it's the root system getting old and susceptible to the constant attack of lake based oridness in the air. I can mark it on the calendar when each strain will go. I feel I know enough now to call it scientific fact. Hearing now that it's one of two trays, I find it hard to imagine it's anything else.
Can you get a run-off sample to have a sniff at? Dig a little maybe? I find h202 holds it off a little, but basically live with it at this location.

I'm not saying it's the problem, I'm just trying to gather evidence.
Perhaps it's dead tissue for other reasons, and levels of airborne mold are high enough to of not waited to invade. A stronger plant cell offers more resistance. Hence people load up with things like silicon. While weak tissue is an easy meal. So we could have plant health as the main cause. They don't look perfect, so the roots are where I would start looking.
