I need a little help from my friends...

Howdy all.

New run in flower at day 13. I'm getting what looks to me to be Ca. Deficiency detection is a big weakness of mine, so I'm reaching out.

Details:

2 Vertical donuts. 6 plants per. Stacked 315w CMHs. Perpetual w/3 bloom rooms

Hempy 2G 4:1 Perlite/Vermi

Jacks 3-2-1 @ 1.5EC/5.8-6.0pH

80F/65% day & night. Goes down to 50% @ day 30

Strains are Cheese, GG4, C99XXX, Bruce Banger & Black Zombie


I started seeing some defs with stretching after putting them from the T5 to the CMH when they were in veg. The T5 they were horizontal, but I set them up vertical around the CMH. I do this to adapt them to vertical and to kick start growth. Since I'm perpetual, I do this with an eye on scheduling. Typical veg time is 3-4 months.

I asked for advice on another thread about why I had the issue when moving them over to the CMH and I'm wondering if the defs are related. I decided to bump the EC to 2.0 and bump Ca up by 100ppm with Biomin. This feed schedule continued into flower.

I thought the feed change would've been enough to counter any Ca issues, but I guess not Bud set looks good, so that's promising. I read a thread recently that implied that once you see a Ca def in flower that it's a lot worse than you think and it's very hard to recover from.

Here are some pics. The issues are contained to the lower leaves.

If it is not a nutrient deficiency it may be fungal in nature.

Less humidity and more air circulation will help if it's fungus issues.

Looks like the first signs of powdery mildew to me... (something I’ve been seeing in my gardens lately)
Really bad year for pm in my area...
Hope I’m wrong and it’s something easier to remedy

Uggh.

I never really considered PM or any fungal issues. Mainly because there are always runs going and if I get defs like this, which isn't always the case, things tend to work out. But now that I think on it, the last run from the get-go, had fans yellowing up and down the plant everyday. The spots on the leaves, not so much, but they'd just yellow and dry up.

Maybe something in that room. Suggestions? Both for the room and the plants.

Thanks!

It helps to give your grow area a break in between grows with a really good cleaning to reduces pests.

Truth

I've been terrible about it the past few runs. Funny how you can trace so much back to 'user error'! My father was a pilot. He believed that 99% of all crashes were pilot error. I agree.

I'll be trying to manage it and limp through this run, but I'll get things straight from here on out.
