Things were looking great until after my last watering with nutes. Gave 1/4 strength using General Hydroponics - Flora Micro 5-0-1, Flora Bloom 0-5-4 and Flora Gro 2-1-6
Let’s get this out of the way:
Strain: Seed from son in law’s last grow, not sure of genetics.
Soil: Ocean Forest in cloth pots
System type: 4x4x80 Grow tent in soil
PH of runoff or solution in reservoir: 6.5 going in and 6.0 coming out
What is strength of nutrient mix: 1/4 strength
Using General Hydroponics - Flora Micro 5-0-1, Flora Bloom 0-5-4 and Flora Gro 2-1-6
Indoor
Light system: During veg - iPower 600w MH Optimized Veg Growth
During flower - iPower 600w Super HPS with flowering red spectrum.
Also the light is on a ballast at full 100% strength. Ballast has 50 and 75% settings.
Temps: Day - 70’s Night as cool as 65°
Humidity: Day - 40’s Night - 50 - 60’s
Ventilation system: Yes, Size - matched for size of tent (son in law’s set up)
Me personally, I would water with a higher PH until my run off read 6.8 or so. I’m not talking about flushing either, just daily watering. I will water with PH at about 7.3-7.4 and collect a small of run off every watering to see where I’m at. Once I get too about 6.8 I’ll return to normal watering…
This is just one route, where you can slowly adjust it with each watering, a flush like @Myfriendis410 said will do you up right also
You should only water when the soil has dried out. This provides an opportunity for the roots to breath and hunt for water. I’m guessing nutrient issues around overwatering. Leaf cupping looked suspiciously like that’s what it was.
This is a common problem and your plant is in pretty good shape over all.
You might get on a regular watering schedule (3 to 5 days) before messing with the ph in yet.
