Sounds like a selective scammer. This kind of thing is typical in the bodybuilding world. The scammer fulfills orders for customers that he believes are well connected/well known in the game and or on internet forums.
Then people he thinks are not very well known he just steals their money.
Yes, I understand. I posted two lots of pics, the ones from the post of mine you quoted which I think were from last Tuesday and then I posted some from yesterday. I think there is quite big positive difference(?)
I'm really not sure if it was Iron, just going on what looked most like the...
I will read it for reference. But I'm certain was not light burn. I really don't have lights very close to plants, I have had them a lot closer before in flower (when running out of head height) and never had any issues (same lights).
My problems started with new growth coming through yellow...
I used Megacrop on my last run and encountered no problems at all. I started to think maybe with this run the bag of MC had lost strength or something but I was really clutching at straws, and things have really turned around now and plants are looking way, way better and I have continued with...
Yes I've seen that chart and probably 10 similar (lol) when I was looking around everywhere to work out what the problem was.
I've also now found out that the PH meter I was using was measuring 0.5 under what it should do!
Got a new PH meter today(decent quality) calibrated it with buffer 7...
Quick update. Things definitely moving in right direction now. I defoliated some of the yellow leaves( so cheating a bit) But the difference from 4 or 5 days ago is really night and day. New growth is coming through looking much healthier.
Still not sure what the problem was but have learnt I...
More growth through today all still coming nice and green. The tiny bits on some of new tips which I thought looked yellow, I possibly think may be nute burn. So at the risk of disturbing things, I decided to change out around a 3rd of res for just plain PHd water, this brought the PPM down to...
Ah OK...The new meter also has EC. IIRC EC was saying something like 2.9ish(today) , which I thought sounded very high! But as new growth on plants seemed to be better I thought best to leave everything alone for now. Also has temp too, which was saying 22c
Today more new growth is through and it is definitely all a lot greener than a few days/week ago. There still appears to be some very small bits of yellowing on tips of some of the new growth(not all) but it looks like a big overall improvement, I think.
Before, all new growth was coming...
Thanks very much for your input. I will see if I can look up the info from my water source, see if anything can be gleaned there. Gonna order a new PH meter from Amazon and maybe spend a little bit more than I did on my current one, and will try your other suggestions.
Thanks to everyone that's...
Yes my pots only have small drain holes in the side of pot at very bottom. I thought would be OK as from what I'd read clay pebbles naturally allow for a lot of oxygen. I don't know.
TBH I wasn't really completely happy with this set up even before problems started this run, even though was...
I'm running 5 litre pots of clay pebbles top fed (flooded 15mins every hour), they drain through a hole at bottom/side of pot onto a table that goes back into res...so is recirculating. TBH I think the pots are really too small to allow the proper root growth, but I've gotten away with it the...
Well thanks for completely clearing that one up for me then! :clap: Can't believe I never thought to think my PH is "too damn low" for soil!
I'm growing in clay pebbles
I feel like I've invested too much time to start again, been vegging 7 weeks not including time to root clones, and other than the yellow top growth the plants don't seem a dead loss. If I can't manage to fix the issue I'm going to gamble and flower them anyway and see how it goes. Even if I...
Yes I used the same lights for last run. Temps have been consistently around 75-77 with lights on and around 71 with lights off. Humidity between 40-50. Which I guess from my reading is a bit on the low side for veg but I wouldn't have thought bad enough to cause the issues I have(and...
No, I don't really have easy access to look at roots. My plants are in 5 litre pots, flood and drain (i think would be classed as) . with only a small hole in the bottom of pots for water to drain.
I think the pot size is too small really and am going to completely change system for next run...
