Nutrient deficiency or lockout?

Its a bit high but not as bad as I thought it might be. I dont check runoff when everythings going ok and I suspect sometimes its about that but thats a sign to adjust runoff and add a feed per day. Dropping ec is never good in my setup once I find the sweet spot. Especially between phenos of the same strain I already grew once.

If you say the others do good at 1.7-1.9ec Id start there first.

There really is a sweet spot and I keep it there by .3 ec so if mine is 1.7ec I make sure its 1.69ec to 1.71ec so its always within 21ppm in range going in. Then going out I try to be within .3ec.

When I say adjust runoff I mean let it runoff longer than you where, you can up to a certain point and that a lone would help lower ec. So if you feed for 30 sec add 15 seconds. You can runoff to a certain point that it a lone could lower the runoff ec but I wouldnt drop ec or raise it, Id bring it to where it last was that made it to harvest. It sounds like its close to its sweet spot.

Heres my Jellysickle by In House Genetics. 3 wks later just about since I found her sweet spot 1.2ec into flower reduced from 1.7ec. I just made sure the coco doesnt dry back dry but still moist when the next feed comes in. Let it run off good and thats it, havent checked runoff.

Soon as its not leaving water on my hands when touching the fabric pot I feed again until Im feeding not long after its dry to the touch almost, “almost.” As a bare minimum or else its ok if its overlapping a bit, its not hurting it but when youre trying to have an appropriate x amount of feed per day and its already 8x-12x its ok. It should at least feel wet, just not sopping wet or bone dry.

I flushed her with 10 Liters at 1.0 EC and the last bit of run off came out at 1.7 EC. Should I flush her again later on when I feed next? Or do you think I should start feeding now @ 1.6 EC?

Somethin aint right which I was expecting at first but the runoff test was ok a bit high. This tho isnt sounding good like there is a lot of salts stuck in there. Thats what florakleen is for but if it was so great it would of peeled dried fertilizer straight off my equipment but wasnt any better than just water.

Maybe the test isnt being done right or the first test wasnt accurate. Id give them the ec that last got them to harvest if its the same strain just diff pheno. Then add more feeds per day, maybe start by adding two more feeds for faster results and let them runoff substantially almost like flushing. It basically is.

I tested the run off of this little plant I've been feeding and the run off was 2.9 EC lol but it doesn't seem to be showing any signs of nutrient problems. I've reduced my feed back to 1.6 EC I am just going to hope for the best

I know you cant really feed more than 2x a day but this what I mean with 3 gallon even if you had 60 gallons for two plants. It will just chug through it.

Yea I just saw how dark they are then fadin and spotted out so it may of not been a good ec for it to begin with. I guess its not impossible for two phenos same strain to need different ec. 9/10 though when it acts up like that when all was fine for others is the salt build up.

It may not be giving issues for a particular plant now but Id think if it does do it that this 9/10 is usually the answer. Id say its a newer grower mistake I made myself a lot before just making sure frequency and duration of runoff was good to begin with.

I think where I went wrong is when I went into flower I stopped checking the run off EC and now it has built up with salts in the coco the EC has spiked and that's probably why I am having issues with them. When I get some money together I will buy some 100 Liter buckets so I can feed them 5 times per day and I think that will help to stop the salt from building up. I will also check the run off EC more frequently on my next grow. I've kinda messed up but I guess sometimes it happens

Now I think about it it didnt raise yield to have 3 gallon over half gallon. I fed them 1.1ec 4x a day and actually got less with same veg time. Whats weird is one of those plants I mothered and perpetuated till this day and when switching to half gallon it needed 1.7ec now. I guess thats evidence when they say root mass plays a role in ec which people agreed or disagreed.

I just dont get certain traits like tree trunk like stem and 11 tip leafs but those are also a grow from seed thing. Really not much difference just easier to work with now that I have 6 clones at a time in flower.

Ive gotten some seriously fat colas but idk about this run but could be due to gas lantern routene for veg lighting or just the season or both. Its cold as hell in basement veg tents. Might be just me though could still be a good run in that particular tent.

Id say I have had fatter buds and colas than when I did 3 gallon pots. Its a plant training thing but trained or mildly trained it should of yielded much more than my half gallon pots if it was really worth it. Maybe if you veg twice as long but whats your footprint of tents/plants? For example I do 2.5x2.5’ to 3x3 size plants in tents of that configuration.

So if you have like 4x4 plants because space isnt an issue thats one thing but if your space isnt much bigger than mine Id worry about them being to packed and rh being sky high and molding.

Not more than 2 times a day? How about 5 times a day?

Two times a day is absolute bare minimum for growing in Coco Coir in flower, those numbers are closer to running Pro-Mix ie peat in flower.


4 plants in a 4x4 vegged for 36 days of veg from sprout and 37 days from flip.

Being fed 5x a day 1.0-1.1 EC pH ~6.3 in flower. I start out feeding once a day during seedling stage and add as the plant progress I keep on adding feeding.

I almost feed identical from start to finish. The only thing I really change is how many feedings to keep pH and EC in optimal range as the plant grows. You won't achieve that with a wet/dry cycle growing in soilless.

You want to keep EC and pH as stable as possible and repeatedly move the off gases as often as possible for better and faster growth rates.

Cheers!
