I'm growing 9 plants in 100 litres of NFT Gro-Tank. 8 of them look pretty nice but that one looks like it's dying slowly. They've been 10 days in the system. This got worse after I changed the reservoir and put the pump on 24/7 yesterday (it was 30min on 30 min off before). I already put the pump back on only half of the time, do you think that's wise for a week or so, so the roots get more air? Please help. It kind of looks like calcium deficiency (to my noob eyes) but it's only got worse after keeping pH at over 6 a few days. Here are the infos:
Pics below.
1. Are you growing from seed or clones?
9x Dinafem Critical Plus 2.0 fem seeds
2. How old are your plants?
3 weeks 3 days since seeds popped, 10 days in the NFT
3. How tall are your plants?
8 inches? Trying to keep them low, tying them to the plastic.
4. What type of hydro system are you using?
Nutriculture NFT GT100. Also called Gro-Tank.
5. What brand/type of nutrients are you using?
Hesi Grow, Hesi SuperVit, Rhizotonic, Cannazym
6. What is the Ph of your nutrient solution?
5.8-6.5, checked daily to be in that range.
7. What is the PPM/EC of your tap water?
0.15 EC
8. What is the PPM/EC of your nutrient solution?
0.84 EC
9. What is the temperature of your nutrient solution?
68-70F/20-21c
10. Does your PPM/EC show a rise or fall when you do your daily PPM check?
Rise a little I guess, because I give it nuteless water to keep it at the same level. Not much tho as the tank is large and the girls small.
11. Does your pH show a rise or fall when you do your daily check?
Rise
12. Do you foliar feed or spray your plants with anything?
No
13. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights")
600W HPS
14. How close are your lights to the plants?
3,5 feet / 110 cm
15. What size is your grow space in square feet?
15 sqft.
16. What is the temperature and humidity in your grow space?
Temp ~72F, humidity I don't know but I keep wet towels hanging from the tent rafters.
17. Have you noticed any insect activity in your grow space?
No
18. How much experience do you have growing?
less than 10 harvests, more than 5.
