Soil Growers:
1. Are you growing from seed or clones? - Clone only
2. How old are your plants? - The ones in this picture are about day 40-43.
3. How tall are your plants? 6ft
4. What size containers are they planted in? 30 gal smart pot
5. What is your soil mix? Pro-Mix w/ Myco. I recycle my soil and cut it 8 parts old with 3 parts new soil.
6. How often do you water and what type of water do you use? De-chlorinated water, Feed every 3-4 days
7. What is the pH of your water? 6.6 on average
8. What kind of fertilizer do you use and what is its NPK ratio?
9. Do you foliar feed or spray your plants with anything? I foliar spray neem & sns 209 every 14-18 days. I foliar with cap's benny teas once every two weeks. All foliared with lights off
10. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights") All Gavita 1000W DE. Total W for room is 16k
11. How close are your lights to the plants? 2-3ft apart if not more.
12. What size is your grow space in square feet? About 600 sq ft. 20x30 area
13. What is the temperature and humidity in your grow space? Day temp is 75-79 and humidity is 60. Night time temp is 63-68 and humidity varies on if my de-hu decides to work that day but generally stays about 55-65.
14. What is the pH of the soil? Have not tested yet
15. Have you noticed any insect activity in your grow space? Fungus gnats - Due to overwatering. Sticky traps, letting the pots dry a bit, and SNS 203 have mostly eliminated the problem.
16. How much experience do you have growing? About two years now. Still have a lot to learn

This happens every run at about week 5. I've been thinking its a nitrogen issue so I bumped up my base N but it has not fixed it. My other opinion is i may be over-feeding ferts.

For my base I run Natures Nectar. For my ferts I run with Aliens old feeding schedule. I can post my entire feeding schedule if someone is smart enough to look over it and let me know what Im doing wrong (Maybe I can pay you a little bit for your time or something?)


Anyway, looking for some expert diagnosis on my plants so I can start working to make them more healthy.

Sorry about the invalid URL. How do I upload directly to the farm? It seems it won't allow me to link imgur posts.

I'd say pH of your soil is out of whack and your plants have problem utilizing P. Most likely salt build up due to over fertilizing. Flush with 1/4 strength nutrient solution until your run off is the same as the solution going in (pH/EC).
