Hello Day 44 from seed. Day 2 of 12/12. Humidity was really high last few days so I instaled dehumidifier in the center of room and humidity is now 50-55% day and 65% at night do muuuuuch better temperature is 25 day and 20-21 at night. I had to water them Today. They really started to drink. Especially the right in the Back.
EC 1,9 - 2,0 pH 5,6. I Think I will have to raise my pH to 5,8 because some necrosis starts to appear on the mature leafs which May suggest magnesium and pottasium deficiency. This two elements better absorb at pH 5,8. I will give it a try if raising EC wont help next week. Light is set on 300w now and will changed to 400w next week and then to 500w next week.
I also did first defoliation of the plants 2 days ago. I removed all of the lower branches and leafs. Another will be done if necessary
Looking good there bro just remember that any unused nutrients can bind to coco and build up and an EC of around 2.0 is already very high (for coco).
I mix in some cal/mag with the nutrients then feed to runoff every time i water. Max is 1.3 at mid bloom for a few weeks then i reduce it slightly over the last 2 weeks. This avoids a load of flushing and seems to produce healthy plants. I occasionally measure runoff EC to see how much they are getting through The ph issue divides people but i go for 5.7 - 5.9 during the stretch stage/early bloom. If your using chelated nutrients the ph is of less importance (in theory) my tap water is usually around 9 so i always adjust it to within range.
Thanks for the advice! I appreciate it! I am still kinda confused about the EC I was told that the advanced nutrients are Just different about the EC. That I shouldnt even use EC meter because when I mix them acording to their charts I get EC about 3,2 at full Bloom! And thats their recomend dose I asked about this my friend that works in hydro store and He told me that many of his friends were confused about this but it was Just Fine and plants grow great
Its Just really wierd that I should lower the dose to almost a 1/3. I always measure my runoff and it was EC 1,9 last time with pH 5,6. I use a lot of bacteria and fungui and Micro organisms in the Coco so they might eat that all up will se… I will check the runoff for now. In conclusion: the build up hasnt start after 3 weeks in big pots and they still look hungry rather then overfed. PH is good and EC is good. Omg thats complicated
Nutrient manufacturers want to sell plenty so it’s in their interests to get customers to use as much as possible. Also the majority of them use RO water to develop their formulas so if you use tap water you have to take that into account and reduce the feed level accordingly. I know a couple of growers who in the past pushed the EC as high as 2.2 but this was with inert mediums like rockwool or perlite. They often got foul tasting buds which could not be sorted by any amount of flushing. I suggested dropping the EC to around 1.4 at max and that sorted the problem. According to Mike from Mandala Seeds most plants cant use these high feed levels anyway and i’m finding this to be especially true with coco.
My Mrs only grows autos in her tent but she follows my advice about feed strength. She still has well over 6 ounces of green crack buds in jars from that last auto and we have smoked at least an ounce of it. It tastes nice and sweet cos it was never fed more than EC 1.3
I use RO water I also checked my last grows and everytime I had issuses It was probably because of the EC higher than 2,0. I will give it a try. I can always feed them more right? Next time I will raise the pH to 5,7-5,8 and lower the EC to 1,6 and then to 1,3. I guess I will have to water more frequently now because they really started to drink a lot. The runoff will tell me more
Hello. Day 48, 6th day of flower. Everything prety much the same.
I decided not to lower the EC. I kept it at 1,9 and pH 5,8. I still Think that they are hungry. But that mightcaused because of the high EC what a mystery. But the runoff is still the same as intake and pH is also the same. Omg I am so confused. Only thing that is visible are necrosis on big fan mature leafs which suggest pottasium deficiency. Any ideas? Any other experienced growers to support lower EC?
Looking good bro, i’m seeing slight tip curl in that bottom picture so your probably right at the limit. Tip burn and clawed leaves is my usual indicator of overfeeding which is often backed up by rising runoff EC. It may be that your plants are getting enough light that they are able to use all those minerals but i’d keep a close eye on that runoff cos things can change in a matter of days. Good luck bro
Hello. Day 12th flower. The runoff EC started to climb so I slowly drop the EC. Today was EC 1,7and pH still 5,8. No leafes damage ocures on the new grow. I doubled the Cal-mag and that seems to solve the problem. I also raised the pH from 5,6 to 5,8.
Looking good bro! the EC rising is to be expected when using a high strength in coco as the unused salts bind to the medium. Plenty of runoff helps prevent it going way too high.
btw it was always recommended not to change anything too drastically like doubling the calmag, unless you were using way way too little and they show serious deficiency which they don’t appear to do. Also remember there will be some cal/mag already in your grow/bloom nutrients, just not enough usually for growing in coco
Thanks I didnt exactly “doubled” the dose…In first week of flower is recomended dose 1ml/L of Cal-mag. After two weeks I should raise to 2ml/L. I Just used 2ml/L in first week instead of third they look great.
About the runoff. How can I do some bigger runoff/flush? They Just sit in the ground with no space Under them. Should I take them out and flush them over a bucket for example? Thanks
You need runoff from coco to prevent salts building up so whatever is easiest for you. I put them in a 20L bucket and make sure i get at least 15 preferably 20% runoff and sometimes much more. They recommend you water coco to runoff every time and never with just straight water. Always use a low strength nutrient mix for flushing if you suspect you have been overfeeding or the ph has drifted
Hi guys. Day 15 flower. Stratching is on the menu but not so agresive as I would expect… I guess I am used to sativa Stratching and not indica
EC 1,7
pH 5,8
temperature 25 day. 21 night
Humidity 55 Day, 65 night,
12/12 Light
I pumped the Light to 450w yesterday
Advanced nutrients feeding
Bottom right plant is Peyote critical. Rest is blue Shark. Blue Shark has slightly pale Green color. I am wondering if they would like to eat more than the Peyote critical. Will see everything else is Just Fine.
Hello day 19 flower. Peyote critical is fatting up prety well Blue Shark is little bit behind but doing Very much ok
EC 1,6
pH 5,8
temperature 25 day. 21 night
Humidity 55 Day, 65 night,
12/12 I will raise the Light to max power on day 21.
Advanced nutrients feeding
I also raised the smallest plant so she is closer to the Lights I Think she will love it.
The solo plant is from day 14 before last defoliation
@Fisch looking great in there mate what strain/s are you running there .?! Excellent potential for a great yield and nice plants too.
I was looking at that fan yesterday mate, what’s it like that oscillating fan for tent like ? I want an oscillating fan and this SEEMS to be good. Thoughts bro .?
Any info appreciated.,
Cheers mate …!
I bought 2 @Gaz29. Both squeaked and the end of each oscillation mate. I managed to fix one of them with an abrupt tap of my hand. The other one I couldn’t fix so I stopped it oscillating. They do give a lot of air movement and both have been running 24/7 for more than 3 months now without breaking down on me. I do recommend them if you can stop that horrible noise
I pumped the Light the max power 500W! Things are going to get crazy
Temperature day 25-26. Night 21
Humidity day 55, Night 65
EC Today 1,55 and pH 5,8.
I also defoliatiated some big fan leafes to have better air movement. Its prety crowded.
I have to water every 2 days with 1 galon of water each plant. They really drink a lot. They look absolutly beautifull and I couldnt love them more
First Frost is also here and it smells absolutly beautifull. Strong Orange candy. I cant wait…
Day 44 from seed. Day 2 of 12/12. Humidity was really high last few days so I instaled dehumidifier in the center of room and humidity is now 50-55% day and 65% at night do muuuuuch better

Thanks
where’s the pics?
too.
I Hope in big yield as well. The plants with the Light really got pottencial
