My grow is about 5 weeks from germination.
I am new to the site and dont know where to fill out the ticket info I keep reading about so I will give a breakdown of what I do know.
Strain: WW Fem Purchased from ILGM
System: DWC in 5 gal drip ring system.
Medium: Hydroton rinsed well prior to grow
PH: 5.8 - 6 in all 9 buckets
PPM (with nutrients) 800-900 ppm
Nutrients used: Foxfarm GrowBig and Foxfarm Bloom used together as per instructions.
Light cycle: 18/6 VEG
Lights: 2 - 1000W HPS
co2: approx 1100 ppm (on auto ppm metered regulator)
Temp: High @ 81 F and lowest at 62 when light is off
Room dimension approx 10’L x8’W x7’H
RH: between 35% & 45%
I began noticing that the leaves and the plants as a whole began looking droopy and the growth seemed to be quite slower than previous grows. I have began topping for more top colas which has worked well and I also have pruned a little on the bottom 1/3 of the plants. Noticing things getting worse in the last week, 2 days ago I decided to flush the systems and replace the solution in the resevoirs with ph’d and tepid water. The water used was ph’d to 5.8 and has a ppm of 180 straight from the tap. My questions are:
Is this nutrient lock-up due to salts?
Should I be flushing with straight ph’d water?
If so, how long?
Any other insight to my issues even if it appears off topic would be greatly appreciated.
Thank you, Hydro Red
