These 3 White Widow, though planted at the same time, are a few days apart in terms of growth. I am planning on mainlining all 3 and have already topped the first plant about a week ago. I'm using individual 5 gallon buckets with 3 gallons of water in each.
This is my first indoor grow so I went with just the basic Advanced Nutrients trio. Aged tap water (126ppm) . At first I used just 5mL of each Micro, Grow and Bloom per 3 gallons of water. This brought it to around 326ppm.
After my most recent res change 4 days ago I started noticing the spots form in the top-middle of the oldest leaves. It seems to move from the oldest leaves up. It doesn't affect the growth tips above the leaf but it goes past them to the next set of leaves. I wasn't terribly concerned at first but since I topped the largest plant it started showing in those leaves and as you can see they are pretty much done.I removed a full gallon of water from each bucket and replaced it with aged tap water PHed to 5.9-6.0. PH is set in each bucket to 5.8-5.9 but I let it drift up and down and only reset when it's below 5.5 or above 6.5. This brought the ppm to around 206.
The condition persisted though and I scoured the net to see if anything matched what I have here. I thought at first it was a magnesium deficiency but I assumed with my PH where's it's at and the nutes I'm using that wasn't the case. I thought perhaps it was my humidity as it is really dry in my tent (just above 25% most of the time). Temps are steady around 75-80 with lights on and down as far as 68 lights off. Bearing in mind that I'm using a single 600W LED panel and a 4" 200CFM inline fan with carbon filter. I tried the suspended towel in a bucket of water which allowed me to get the humidity up to a 30% average at 75 degrees. But that's it... Is the condition I have here because of this or is it something I've missed? I don't have a speed control on my fan but even if I did I'd be wary of lowering it much since the exhaust vents out a window and it's -10 outside.
Any help or advice would be much appreciated. Thanks so much for taking the time to read.
