Day 43:
- Watered with 30% recommended strength Remo Nutrients
- Hooked up a/c unit, vented directly into tent via 4" duct.
- Increased light intensity from 70% to 80%.
- Increased exhaust fan speed from 30% to 50% to maintain negative pressure with a/c blowing into tent.
Day 44:
- No water
- Lights on temp: 73-79F
- Lights off temp: 65-73F
Day 45:
- Watered with 30% recommended strength Remo Nutrients
Day 46:
- Watered with 30% recommended strength Remo Nurtients
Day 47:
- No Water
- Increased light intensity from 80% to 100% for approximately last 6 hrs of "lights on"
Day 48:
- Watered with 30% recommended strength Remo Nutrients. Increased "MagNifiCal" to 50% recommended strength due to rust spots
- Unsure if rust spots are being caused by a Cal-Mag issue or possibly light burn...? Only 1 of 3 plants showing those spots, on upper and lower leaves.
Brown/rust spots have been increasing on one of my 3 plants.
Appearing on upper and lower, newer and older leaves. Does not appear to be a light/heat issue.
Treating it as possible Cal def by increasing cal-mag nutes.
hey there , calcium was the symptom but light stress was the culprit i'm afraid, you gotta lower your lights to around 30cm (max) - 40cm (min) it seems close, but in fact that's pretty normal, that plus a regular regimen of cal mag and the problem should stop spreading almost immediately. Hope this helps ! 🚀
@CRiSPrGrow, Cheers! I"m just hoping these ladies can stick it out at least another week or so. I don't see "EM-2" recovering too well but hopefully she makes it through!
...and ya, been meaning to jump on the chat and say hello. 😋
@CRiSPrGrow, Thanks! Wasn't sure if it was Cal or P deficiency. I've increased both my CalMag and phosphorus so hope things start looking better before final week of flush.
Thanks again for the input!
Hi @VanCplGrows! Nice ladies in there 😍 I'm thinking more of a Phosphorous deficiency, considering you're giving loads of nutrients, I think your plants had enough Calcium and Magnesium. My bet is that you're having salts buildup in your medium, because of an intense feeding schedule and probably a lack of runoff, your rootmass is flooded with old nutrients, and is unable to manage nutrients intakes anymore (lockout leading to deficiencies). In this situation I would flush the medium with tap water buffered at pH 6.2, then help the medium to dry by putting a small fan blowing a continuous breeze on the container's surface. Once almost dry, see how this goes, and probably give it a good meal with Phosphorous and Potassium. Affected leaves won't recover but the new ones should be healthy. Hope this will help, keep us updated and happy growing! 👊
Hey @Stick, thanks for the message. Ya, i've sort of started focusing more on the phosphorous rather than Cal-Mag. My feeding schedule for most of the grow has actually been pretty light. I usually feed 2-3 times per week and only with 30% of the recommended dose. It's only been this past week that i've increased the nutrients.
When feeding, i typically only water just until run off starts. When watering with plain pH'd tap water, i tend to water fairly heavily and the run off comes through relatively clear.
I've tried to maintain the idea that under-feeding is better than over-feeding but since i don't have a proper EC meter, only a pH meter, it's hard to truly know what's coming out.
I figure this will probably be my last week of feeding, then will do a 1 week flush, so not a ton of time for me to turn things around but i'll keep your advice in mind to try and avoid any future problems.
Much appreciated! 👍
