I’m with you on the confusion. It should be coming out at least as high as going in.
I was checking out pics of plants they look healthy.
Tell me about it. I think you had a similar issue with the outgoing water PPM in a very high range. Did you stop fertilizing for a while? The plants are growing like a weed, and don’t seem to need anything.
Thank You, keep an eye on them, don’t want them going south
My ppm’s stayed high until I went to Flower. They started dropping fast once they started flowering.
I guess I better keep an eye on the flowering auto then. Weather has been cool and rainy, so they are all doing well on water. I have learnt to let them get fairly dry before adding any. Maybe this auto will start asking for nutes soon.
Pics tonight under the Viparspectra lights. I may need a third one. Hard to see but in the back they are leaning towards the lights.
In the back you got issues Brother. I’m not the lighting expert. But I think @dbrn32 can help on that. It may not be lights But a couple of your girls in the back are asking for some help. Don’t sweat it. Some great folks here they will help out shortly
Good eye!
I’m thinking at bare minimum you need something. just because it is physically lit up doesn’t mean it will have intensity required to grow good bud.
@Dman1969
Thank you all, I agree, although warm weather is almost here and the photos will get all the light they can stand. I will go ahead and get another one for the Autos. Thanks for the heads up
Do you mean the tomatoes and pepper plants in the back?
Awe hell is that what that is!! I guess I don’t have a good eye. That being the case I’m sorry. All the girls up front look amazing to me. I was wondering why just a couple in the back looked so much different! I sit corrected @Skydiver nice work! I assumed that all the plants were cannabis. That’s what I get for assuming.
Yes I have tomato and pepper plants all over, lots of them out of the lights. Just running out of room waiting for warmer weather to plant them outside
Lol, but still a small auto in back not getting lots of light but I can move around, and the small photo in the very back is getting light, perhaps not adequate but it is being supplemented by just over 12 hours of , and it has a way to go.daylight
@Bulldognuts, @QueenCityB, @Dman1969, @CoyoteCody, @MidwestGuy. Gentlemen, since you all have turned me into a Geek with all these PH and PPM and other abstract measurements, I have downloaded a LUX app to the cellphone. It reads either in Lux or FC. I need instructions in what numbers to look for. I have the basics as far as putting it on the top of the canopies. A couple of the regular WW planta have grown from almost 24" below the lights to 15" this morning
Lux isn’t really too relevant. Your plant doesn’t see lux, it sees PPFD (Photosynthetic Photon Flux Density.)
The app can read in either Lux or Foot candles, which one and what numbers am I looking for?
Seedlings: 300 PPFD
Veg: 600 PPFD
Flower: 800 PPFD
Direct sunlight is between 32,000 and 100,000 lux depending on where you are in the world, but PPFD is what you are really looking for.
I believe HLG has a lux to ppfd conversion calculator, dont know how accurate it is, but I’m at 38,000-40,000 lux at the top of my canopy in week 6 of flower.
It’s for HLG lights. Jetlag is using a Viparspectra, which will have a different spectrum.
