First time grower here. I am on week 3.5 and my plants seem stunted and showing signs of nute deficiency/ excess or lockout. The have brown spots on lower leaves, they turn rust gold (see pics). These showed up after transplant. Also seem to have weak unhealthy stems, plants are leaning to the side instead of upright.
White Widow Autoflower Seedlings were planted under a seedling cfl for first 2 weeks in sterile seedling soil.
Received my grow tent and light about a 1.5 weeks ago and transplanted the into FFHappy Frog put in tent.
Tent: Vivosun 4x4 x 80"
Ventilation: Vivosun 6" inline fan with filter setup with Inkbird temp controller to cool tent and ventilate
Light: MarsHydro TS 2000 set on 100% 18" above canopy, set on timer 20hr on/ 4 hr off
RH: kept between 45-65%
2 small air movement fans, one on the bottom and one on top of tent
PH of soil out of the bag 7.0 using a standard in soil PH, moisture, light monitor
Water: distilled water PH 5.6
nutes: Bergman PF Seedling Fert N11, P 40 K 13 half strength
Just switched to 1/2 Growtime Fert N 19 P 5 K 20 and 1/2 Swwdling Fert today. Watering about every 3 days when soil almost completely dry.
Pre water readings of water with Nutes: PH 5.2 ppm 426 EC 885
Average readings of plant RO:
pH 5.7. Ppm 1300. EC ranges 2130 to 3020 (seems high)
Do I need to flush?
Thanks for any help. Would really like to get this corrected. Cheers.
