They will be just fine. At least as far as the PPM strength of the nutrients.

@Mañ'O'Green Awesome! Just making sure, I know some schedules say no more than 400-500 at this stage. Just checked and PH shot up pretty quick, plants got darker in color as well. I think they were thirsty!

If you aerate your water for 24 hours before adding nutrients and adjusting PH it will be more stable.
I thought you posted roots were in the res? cannot get thirsty if they are in the res?

They are nice and long now! I was implying perhaps their nutrient uptake caused an increase in the PH. Maybe hungry is a better word ?

I let the water sit out for 24 hours before mixing!

You should run a little air stone in it; it helps to precipitate the calcium carbonate and that in turn is what helps stabilize the PH. No way are the plants large enough to effect the PH. The first time that that will happen due to plant exudates is when they bump into high gear of flower. You need to watch closely at that time because it can happen rapidly with huge swings.

More than likely the water is giving off the calcium carbonate as the air is moving through it. Another possibility would be you did not get the hydroton PH stable before using them? Even the clay pebbles that claim to be neutral should be soaked and PHed before use.

Sage advice. Particularly when it comes to the rapid swings during flower and cleaning the hell out of the medium.

Hydroton is stabilized. Soaked in 5.4 for 24 hours and washed off after! Definitely needed an air stone run through the new soup I mixed, I think you hit the nail on the head with that one. Thanks for the info , it is extremely helpful. I brought the ph down to 5.8 gradually, hopefully the rez will remain stable now!

@Mañ'O'Green I got pythium! Funny smell and brown roots. H202?

Nope I recommend and use Botanicare HydroGuard. If you read my basic bubbleponics thread you would already be using it!

Hey there! Actually after reading your guide I went and bought hydroguard. I did add about 50 ml to the soup I mixed up sunday. Must not have been enough? That or I added it in the wrong sequence. Regardless there is pythium now, so I was wondering if I could sterilize the soup with h202 and add a stronger dose of hydroguard later? Or should I add more hydroguard?

I saw your response in the infirmary as well, I actually did follow your advice on adding the seedlings to the net pots, I then gradually lowered the water level as the roots dipped in, they have a significant amount of space to breath now.

My concern is getting rid of the pythium and re-establishing the beneficial bacteria.
