Things are looking better this week. I noticed a couple of yellow tips and I decided to check the calibration on my pH meter and it was off again. I watered a couple of times with water that was too acidic so the next couple of times I water I'm not going to do any pH adjustment and hopefully it will balance back out. I figure it's too early for the yellowing to be coming from a lack of nutrients so I'm going to continue to hold off on nutes for at least another week, as long as there isn't any other yellowing. Going forward I think I'll just calibrate my pH meter before every watering, even though it's a total PITA. I'd rather not have to wonder.
Plant 1 is the only plant that I'm not really happy with. I'm just going to assume it's a genetic problem that is keeping it so small but I'll continue to let it grow because it's not taking up a lot of real estate or anything. So far plant 6 is the tallest but it doesn't have me worried about deciding against doing any training, but that could change. Plants 2 and 4 are just about the same height. After they're all done stretching I'll probably have to rearrange which plants are in the center just for even light coverage, but if I can I'll leave them in this arrangement.
On a side note, I'm going to update my first grow journal in a few days because everything has been curing for just about 30 days so I can finally dig in and give an accurate review. My life got extremely busy and hectic when I harvested and now I've got the time to do a proper review, so look for that soon. I'll change the cover image when I update it.
@MisterPandaBear, Light used was an HLG 550 3000k V2. Tent was a 4x4 Gorilla Grow Tent. Exhaust Fan/Can was a 6-inch Vivosun package on Amazon. Main air circulating fan in the tent was a Honeywell Quiet Set. That's all of the equipment I can really think of that matters.
Some lovely colors on that lady. Fantastic work. Beautiful purple color starting to come in nicely. Keep doing what your doing and best of luck the rest of the way growmie
Just wanted to add that I got the opinions of some growers I respect and they have diagnosed the problem as too much calcium. Lesson learned for next grow. I'm not going to supplement calcium in any form until I see an actual deficiency that isn't caused by lockout, which I may or may not be able to recognize, but I'm willing to try ;)
I'm posting this on day 43. I watered a few plants tonight and did the same nutes for all of them, but used 10 drops of pH down in one gallon, and no pH down or up in the others. All gallons used had the same pH (6.5) when I measured them with a digital meter. I then went and tried the pH test kit that's done with drops of test solution that came with my pH down/up kit. That also shows the water is at 6.5.
I tested run off for pH. The gallon that got the 10 drops of pH down produced 5.9 run off. Liquid test confirmed it was very close 6.0. The other gallons produced 6.1 run off and liquid test was a tiny bit greener meaning the pH was slightly higher.
I think I'm going to flush with some straight up plain old water that hasn't been pHed and see if I can get the soil to be less acidic. I think I finally understand what's happening with the multiple deficiencies and I'm hoping that things haven't reached the point of no return yet.
Is it normal for tap water pH to fluctuate?
