Hi all,
First off want to thank anyone who takes the time to read my post and that I greatly appreciate any input or advice. This is my first post and I apologize ahead of time if I didn't properly follow guidelines or something like that.
I'm currently about to start the 5th week of my flower cycle for a run of Tahoe OG that was from clone(vegged about 3-4 weeks). In the beginning of my flower phase I was using a RO filter for water but my filter desperately needed to be changed because the PPM of what i was getting was around 600. The first two weeks I had no choice but to make due with the 600 PPM so I adjusted my volume of nutes so that the total ppm was around 1000(400 ppm of nutes). I'm using Advanced nutrient sensi bloom line and I'm running everything in 6" hugo blocks with a drip system that runs 7 times a day for 3 minutes each time every two hours. What really threw me off is that I was checking PPM every day and it stayed the same as what i put in so i assumed the level was correct and the plants were eating what they needed.
About 3-4 weeks into flower i noticed that about 60% of the trees seemed to be stunted and the buds were not getting any bigger in respect to some of the others in the lot. I also noticed the foliage was a very dark green and i was getting the claw on a lot of the new growth which indicated a nitrogen toxicity. It was around this time i finally got around to switching out the filters of my RO system. I flushed for about 2 days with RO water and the second day i added some Cal-Mag because i had some signs of a minor magnesium deficiency (lower leaves showing interveinal chlorosis).
After running RO for two days about half of what was stunted seemed to snap out and buds started enlargening again. I then went back to running nutes at half strength around 600 ppm and it would rise to about 700-750 as i let it run. This time i added Hi brix(molasses) at half strength as well. I did this for a week before i realized that about 30% of the batch still has not gotten any bigger though the top growth is reverting back to a lighter green and THC crystals started forming but the only thing is the buds are just not fattening up. It seems like some of the leaves that looked like the claw are also starting to revert back to normal shape. I switched back to running just RO water thinking that i maybe did not flush enough. I read that you need to run through about 3x the volume of water as your growing medium and i probably did 2/3 of that.
Did i not flush enough? What are some signs i should look for to indicate that nitrogen toxicity has been corrected? Is there anything else that i could be missing that could cause buds to stop growing? This is driving me nuts. The structure of the plants are wonderful and its sucks just watching day by day them not reaching the full potential they can. Sorry for the long post and once again thanks to anyone who took the time to read through it.
Hydro Growers:
1. Are you growing from seed or clones? Clone
2. How old are your plants? 3-4 weeks veg, beginning of 5th week of flower
3. How tall are your plants? range is 20"-28"
4. What type of hydro system are you using? 6" hugo blocks with a top drip irrigation system running 7 times a day for 3 minutes every 2 hours.
5. What brand/type of nutrients are you using? Advanced Nutrient line Sensi Bloom, rhino skin, big bud, bud factor x, bud candy, voodoo juice, b-52, and recently started adding hi-brix molasses.
6. What is the Ph of your nutrient solution? 5.7-6.2
7. What is the PPM/EC of your tap water? using RO water that comes out to around 30 ppm
8. What is the PPM/EC of your nutrient solution? Initially running at around 1000ppm with 600ppm of that being offset by dirty RO filter for first 2 weeks of flower cycle have since then replaced filter.
9. What is the temperature of your nutrient solution? a little high 72-77 farenheit, 77 rarely more within 72-75 range.
10. Does your PPM/EC show a rise or fall when you do your daily PPM check? hard to say because i have had to switch from 1000 to RO to 600. Currently around 600 ppm and it rose to around 700 but that could be from previous concentration of nute solution...
11. Does your pH show a rise or fall when you do your daily check? For awhile i would ph down to 5.8 and after one run through system ph would go up to 6.0-6.2 however it seems to have leveled out and is consistently coming out around 5.7-5.9 after being run through system.
12. Do you foliar feed or spray your plants with anything? nitrozime and neem oil during first 2 weeks of flower and in veg.
13. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights") 1000W hortilux HPS on parabolic hoods every 4x4.
14. How close are your lights to the plants? about 24"
15. What size is your grow space in square feet? 17x24
16. What is the temperature and humidity in your grow space? at night temps are around 68F during lights on canopy temps are around 84 F with humidity range 40%-70%
17. Have you noticed any insect activity in your grow space? Some mites, gnats, and an aphid or two but nothing that is out of control, i had hung up a hot shot no pest strip for the first couple weeks of flower.
18. How much experience do you have growing? about 2 years now
