been getting some issues round wk2 of 12/12 with cheese and power kush
lower leaves wilt, margins go crispy and they eventually fall off
stays lower down the plant, they do get big so the lower areas are not so well lit
although i do prune the bottoms out pretty hard before 12/12
doesnt seem to affect bud quality or yield and growth rate is fine,
just thinking maybe it could be better
1. Are you growing from seed or clones? clones
2. How old are your plants? 8wks veg 2wks flower (longer veg than i wanted due to delays)
3. How tall are your plants? 1.1m
4. What type of hydro system are you using? coco
5. What brand/type of nutrients are you using? canna coco A+B, canna mono nutes cal and mag, canna PK13/14
6. What is the Ph of your nutrient solution? 5.8 - 5.9
7. What is the PPM/EC of your tap water? 0.08 (RO)
8. What is the PPM/EC of your nutrient solution?
right now 2.1 including 2ml/10L PK13/14 and 0.5 ec cal (4ml/10L) and mag (2ml/10L)
9. What is the temperature of your nutrient solution? 20C
10. Does your PPM/EC show a rise or fall when you do your daily PPM check? runnoff is 2.0 EC
11. Does your pH show a rise or fall when you do your daily check? usually the same or slightly higher (6.2 max)
12. Do you foliar feed or spray your plants with anything? only early on in veg AB 1ml/L, rhizo 1ml/L
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? 1ft/30cm
16. What is the temperature and humidity in your grow space? 28C day, 19-23C night, RH 60-70% veg, 40-50% flower
17. Have you noticed any insect activity in your grow space? got some black flies kinda like a fungus gnat with larvae in coco, always seem to get these, control with Bacillus
18. How much experience do you have growing? have had a few successful crops ;)
im thinking either salt buildup, phosphorus def (there is no grow and bloom formula with canna just one A+B and PK additive), or some kind of fungus/mold thing??
maybe all of the above...
any ideas much appreciated...
