Hi peeps, I recently got some new maxibright 600w cmh bulbs that supposedly put out 1.6 umols. I swapped them for hps bulbs and after chatting to the owner of the store for a while he was convinced this was a great way to upgrade my lighting and that they will definitely outperform my hps bulbs...

Hi mate, ph and ec remained stable for 24hrs. I have a foliar spray that has added cal mag so i just gave a good spray am now changing res again will do a fresh batch with very light feed of 0.7 and hopefully things start to pick up. Thoughts on POA and as always, thanks for the advice...

Ok mate so do you believe I’ve taken the right steps in lowering the ec ? Also why would they be deficient if ec is rising. Thank u for your advice so far, much appreciated

Did you get a chance to view the photos mate. Res change last night set ec to 0.6 and appears the same now ph also went up to about 6.1 which is also ok

Hi mate managed to get a photo. The yellowing you see hasn’t got any worse over the past week so thats a good sign. The new growth at the top looks pretty green also. I just changed the res and its at 0.6 ec so hopefully it stabilises over the next few days and they start eating again

Ok mate i think I’m going to be forced to anyway with height being the main concern. Having reduced the ec to 0.6-0.8 would you start flowering at 0.6-0.8

Hi mate I won’t be able to get any pictures tonight unfortunately but im just wondering if it will be massively detrimental to the plant putting it into flower whilst recovering from a ph drop. They are still growing up and out

Yes roots are lovely and white res temps good room temps good. I understand the yellowing wont get better just the new growth should be green

So pretty annoyed at myself due to over feeding and causing ph to drop in dwc res which caused a bit of yellowing to the leaves. Having now sorted it by halving the feed in a new res change i am mainly frustrated as i was looking to flip very soon due to height limits! Plant has been recovering...

Ok thanks for the suggestions i have a dome that I mist daily as well. I will put the pump on a timer. I think i could raise the humidity a bit which probably is slowing them down

Hi guys first time taking clones and 10 days in no signs of roots at all by the looks of it, cuttings are in root riot cubes cut at a 45 dipped in clonex rooting gel and sat in a aeroponics cloner with a weak nute solution. They look healthy and have never wilted but showing no signs of roots...

Not great quality photos but roots are only small. No slime, white nor any smell

Gunna change the water as no signs of improvement. Anyone got any other ideads as to what this could be only additive in there other than a+b is silica

Got that mate i have a 60L per minute air pump which is way more than enough for the size i do have roots out the bottom so I’ll just lower the water level to just below the net pot an see how i get on

Hi mate cheers for the reply the only thing you said that might correlate is that the roots are fully submerged. I lnow there should be a gap from root to water but there isn’t so do you just suggest removing some water and see how i get on? Cheers

Hi i have a couple babies in dwc and a few are showing this on lower leaves. Ph is 5.8-5.9 and EC is around 0.6-0.8. With ph and ec in check I’m not sure what it could be? First thought was bad ph???

Hi mate cheers for the reply i just wanted to know as in dwc you can use a ec meter to adjust weekly as the plants change their needs but I couldn’t figure out how you do that with autos

Anyone shed some light please?

Ok so i have been growing in dwc for the past year with some decent success but am going to give autopots a whirl. I have the 15l 4 pit system in a 1.2,1.2,2.0m tent with a 600w hps, will be germinating soon and just wanted to get some advice on growing in autopots and coco as never done before...
