15 1/2 weeks in.

15 1/2 weeks in. Sour Tangie in Coco Loco. Growers Choice e420 with deep red and uv add-on. GH Trio with the basic extras. One 5 gallon, one 3 gallon felt pots. Mid week of late bloom. Week and a half to flush?? Small leaves curled at top. Everything else is looking good. EC 1300, 5.9 pH.

What happened to your leaves? The back one looks like it has a magnesium issue(purple stem). They look pretty far long might be sooner than you think

I've had red stems for a while. Though it was the strain.

Red stems are almost never strain related, imo. She's deficient. The question is, why?

Looks like there are no fan leaves left. What happened to them?

Trimmed the ones covering bud sites.

I have nutrients ready. EC 1275, 5.9 pH. Should I water a bit heavier today flush anything? One week ago the run off was slightly less , EC and pH, than going in. My plan shows these girls going into last week of late bloom before ripen then flush. Need some extra eyes here. Plans don't always work out. Looking for the best end game strategies.

This is the nutrients chart I've been following. Now in the last week of late bloom. I've been keeping the numbers as spot on as possible. I mix one gallon at a time. Would mixing a 5 gallon batch be easier or better? How long will nutrients hold their potency?

like I said I lean toward Magnesium deficiency with the red stems. Sounds like you are putting more than enough nutrients in. PH is a bit too high for coco. Maybe back off overall nutrients reducing K specifically and aiming for 5.5-5.6 PH. The phosphorus in PH down should help uptake magnesium easier and calcium will be in range as well.

I've been looking back on what I've done so far and realized I was mixing the lower dose of CalMag in the nutrients. 1.5 ml vs 2.5 ml. Could that be the difference?

Purple and red stems are not necessarily evidence of a deficiency. Many strains have deeply colored stems or turn dark due to environmental impact, ie prolonged cold

h202 wont last long. Use pool shock or bleach if your tap has too much calcium in it. Calmg only locked my nutes out it didnt stop until I removed it. I was in ro water at the time which is especially supposedly why people use it then.

I find the ec sweet spot and keep it there. Moving the ec by as much as 70ppm or 140ppm really from start of flower to end flower. Then he drops the ec by 280ppm for ripen? I dropped my ec 140ppm week 8 of 10 and leafs all got deficient. If clones I just give them the same ec from start to finish.

following that chart would give me problems left and right and it did when I first started coco and started on that site. People here taught me the rest then 7 perpetual rounds later I learned somethings myself. I just use maxibloom and bleach.

Thats not the only chart, any chart really. Its not going to always play out that way even if I made a chart. Idk thats just me tho. Instead of a chart Id journal and refer to notes and carefully decide from there if youre having issues. It always boiled down to frequency and plentiful runoff. Sometimes I do nothing at all, work its self out. Ive done that a few times.
