i have a couple questions what are you using to check your ph, how often do you calibrate your instrument? how often do you check the ph of your reservoir ? also what instrument are you using to measure your ppfd, 1100ppfd is pushing them pretty hard without co2

I was hanging two lights. Now I have one. Center of plant and top of colas are now at 700 - 900 ppfd according to an app, however accurate that may be. I have considered ph and therefore ordered a blulabs ph meter. I use a bluelabs tds meter for ppm. She gets a new res every three days because she drinks the whole thing that fast. I feed at 5.7 - 5.9. Ph in dwc fluctuates within hours and is impossible to maintain regularly. I assume that is because as the plant eats the tds decreases resulting in a higher ph.

I should also note that over 60 days of veg this process worked perfect. The ph fluctuations I attribute to the plant knowing what it wants, when it wants . It is only mid flower I have begun having this trouble. Thank you

60 days of veg in hydro is alot of time to make alot of roots i assume this is a plant in some sort of tote with a large air stone. how many gallons/litres is this tote?

This is 5gallon dwc. Yes it's a long time. It's put me off schedule something terrible. This was an auto flower that I had to force to flower. It is likely the seed bank sent a photo. It has grown larger and veggied longer than anticipated

might i suggest moving the net pot and the roots to a larger container i suspect a larger volume of water surrounding the roots should alleviate a lot of problems

That's a hell of a suggestion too as oxygenation is limited by the root/water space. However, I don't have the lateral or vertical space. This plants veg period and the flower period now has put me 8 weeks behind. This is why I have decided against autos. I need control of these cycles for the space and the climate. Thank you for suggesting that, it is definitely valid, I wish I could.

Unfamiliar with these products, but mixing the wrong one before the other causes lockout as well.
