I’ve been attempting to grow some white widow autoflower from Neptune seed bank.
Medium is soil. Tent is 3x4. Dumb but I’m not sure of the lights. Using two different cheaper leds.
Decided to give foxfarm grow big a shot a few weeks back and ever since they’ve been looking worse and worse. ( looked fine before the nutes). We were showing pics at our local grow store and they said to try cal/mag supplement. We’ve been adding it at watering. We also attempted to flush soil thinking we might have blocked nutes when trying grow big.
Water ph is between 6.8-7.4. We’ve been buying ro water and adjusting ph.
Don’t have a great way to test soil ph at the moment. Oh. I believe the older girls are around week 6. The younger ones will be moved this weekend to a 4x8 with a 4000watt led.
