Day 50 - Terrible start to week 8.. The spotting problem has gotten worse. I've only been able to treat with Cal Mag once (yesterday) and plant doesn't seem to need watering yet today but I may be able to squeeze a 1/4 gallon in later. I'm still proceeding as if this is calcium deficiency. Does anyone looking have any comments? I'm not sure what to expect after treatment and I expect spotted leaves will not fix themselves but I still do expect to see improvement at some point...like no new spotting. I will probably just cut off spotted leaves soon and watch for any new appearances. 😕 Watered 32oz. With Cal Mag.
Day 51 - Watered 32oz. with 1/2 Big Bloom and 1 Cal Mag.
Day 52 - Watered 32oz. with 1/2 Big Bloom and 1 Cal Mag. Trimmed a few damaged leaves. No *new* damage from calcium deficiency noted. Still a few older damaged leaves left but they are close to or in bud sites so I'm going easy.
Day 53 - Plant definitely worse this morning. Please help me figure this out. I took a leaf to local grow store and they think is pH problem. They advise to lower water pH to 5.8 and run full dose of Cal Mag with Big Bloom and Tiger Bloom. Up till now, I've been adjusting water pH to 6.6. Watered 32oz. 5.7pH water with 1/2 tiger bloom nutes, 1/2 big bloom and 1 CalMag.
Day 54 - Still looking worse. Watered 48oz. 5.7pH water with 1/2 tiger bloom nutes, 1/2 big bloom and 1 CalMag. I've been using CalMag and adjust water pH down. Also using nutes. I also opened left side vent at bottom of tent (right side vent has been open for weeks) Not sure what else to do. In case my issue is Rust fungi, I applied Safer brand 3-in-1 Garden Spray (has .4% sulfur) and shut light off for 4 hours in middle of day. I probably should have waited until evening.
Day 55 - Still looking bad. I stopped running humidifier at night on the chance that the high humidity and low temps were causing a rust fungi. This is all very depressing. If it's a calcium deficiency, I'm now treating with CalMag. If it's a rust fungus, I treated with sulfur spray. I don't know what else to do.
Day 56 - 48oz. 5.7pH water with 1/2 tiger bloom nutes, 1/2 big bloom and 1 CalMag. Noticing strange odor from plant which I think is from the Safer brand 3-in-1 Garden Spray.
What to do with vent flaps at bottom of my 2 x 2 tent? Exhaust fan running at ~33% speed with carbon filter in tent as intake. Tent In cold room (overnight temps 45-55*F) , running heater and humidifier in tent. Currently, 2 of 3 flaps tented at bottom of flap to allow air in.
I would close them to keep the heat inside. At this point there isn't much need for them to be open unless you have heat issues and wanted the cooler outer air to get in the tent.
Help! I thought I had this. Is this calcium deficiency? I've been using treated water (1tsp CalMag+ 1tsp Grow Big per gallon). It's just getting worse. See photos and descr. from past few days.
Hey man I just saw your question about harvesting...first the plant isn't ready to harvest yet. Your pistils really aren't starting to die off yet. You have several weeks to go from what I see. The damage on your leaves is a light or heat related issue. I would try to get the light as far away from them as possible so you can push them longer. Good luck!
@HiddenOp831, Humidity too high or too low?
I found a great humidifier (and heater too) that's perfect for small grow tent. Winter here and tent is in cold room with ~25% RH.. That's why I'm running space heater and humidifier in tent.
@Gewroo, totally understand. I’m right there with you. This is my first auto, second grow. And my first grow was just one plant. I’m having humidity issues at the moment that I’m dealing with.
@HiddenOp831, Using plastic 5 gal. pot. I'm not really watching for saturation runoff. I did that initially before first planting to get idea of pot weight. Since then, I've just watered when it seems like pot got light. This seems to be accompanied by the first inch or so of soil to be very dry. I dunno. Seems to be working for me so far. After planting and during early veg stage, I was watering 1/4 gallon every 3 days or so.. At current stage, I'm giving plant about 1/4 gallon per day. I'm also stressing over keeping temperature and humidity in check. Other than that, I have no idea what I'm doing.. LOL
Good choice of seed for your first grow. A couple of them took longer than I was expecting for an auto but I was very happy with the results I had from this brand. Hope you enjoy your grow as much as I enjoyed mine.
Is the spotting happening on the top leaves? if yes, then it is a calcium defiicency, which by the pictures it appears to be the case. The problem with calcium deficiency is that the symptoms appear several weeks after the deficiency is present. At this point there is very little you can do. your water should always have a base of 0.5 EC (250 PPM), if not then you need to add cal mag to get to that point.
@@Athos, Thank you!! Not necessarily on just top leaves.. It seems to have started on lower leaves and spread up. I have cut out a lot of the lower leaves that were looking bad. Now it just seems all over. I have been using CalMag (1 tsp/gal) the last few days and yesterday I treated with Safer 3-in-1 Garden Spray for Rust fungus. I'm really suspicious of rust fungus because I've had occasions were nighttime temps were in the low 60s with 70% humidity. I've since started turning off humidifier at night and just let the humidity drop into the low 30s overnight.
