2 3 gal smart pots sprouted 3/24 (white widow, Bubba Kush
4 5 gal smart pots sprouted 4/10 (3 Blueberry, 1 Galaxy)
Watering schedule 1 gallon water every 3 days PH 6-6.5 PPM under 700.
Tap water is naturally alkaline at 7.5 or so and PPM around 200.
Nutrient schedule is week 3 veg on the drain to waste table on https://www.growweedeasy.com/general-hydroponics-flora-trio-guide
Flora Trio: 1/2 tsp Micro, 1/2 tsp Gro, 1/4 tsp Bloom. Total PPM is kept under 700.
Lights: HLG 100 R spec x2 at 18 inches from WW and BK
Temps 73-81 F with AC 6 in fan running at 4/8 speed.
All plants topped at 4th node once 6 nodes in height
5/8 Soil Slurry Results:
BK: 335 PPM PH 6.8
WW: 370 PPM PH 6.8
Front Right BB plant: 552 PPM 6.7 PH (I've been feeding PH at 6-6.2 to bring down PH since then)
The leaf cuttings are from the Bubba Kush plant pictured in #2. Pic #3 is the White Widow. Pic #1 shows all of the plants for comparison. The smaller plants are about 2 to 2 and a half weeks behind the BK and WW. Some of the newer plants are starting to show the same tell tale signs of WW and BK. Purpling stems, yellowing between the veins which turns into dead spots, ends of the leaf get crispy, fan leaves sometimes twist sideways, some of the leaves seem papery dry, WW especially seems to have leaf cupping issues despite the lights being pretty far away. All I can think of is nutrient lockout due to PPM in the soil being too high or low. I haven't flushed any of them yet because my last grow made me scared to flush since they suffered from so much chronic overwatering. I do water until they have a bit of runoff, but I've become much more concerned with overwatering. Also of note, the soil medium of the plants isn't "fluffy" like when the plants were smaller, but I attributed that to all the root growth impacting the consistency of the soil. Its also possible that the soil was so hot for the first several weeks that adding nutrients just choked the plants with nutrients. However, you would think that the BK and WW would be balanced out by now considering how far along they are. This is my second grow, and I'm getting better, but holy shit I don't want to start flower when I can't even keep plants green in veg. What information have I left out? I know I'm missing something fundamentally simple since the same thing is happening to all 6 of these plants and happened to the last 3 autos. I don't know how I could even flush all 6 of these bastards (26 gallons of soil). I've been thinking maybe plain water feedings for a week, but I'm of course scared that if the issue IS really lack of nutrients in the soil and not lockout, then they will really be flushing. So many symptoms have comorbidity; how the hell can I ever narrow down definitively?
