, I use 600w HID (HpS, mh) and a small LED for spectrum. Light meter just gives me an idea what the canopy is getting.

Anything free, probably won't work. Best option is to buy an actual lux meter, instead of using your phone. They're like 30$ or something, so won't make you starve.

Is lollipoping this late in flower not a good idea? I had a lot of really insignificant bud sites that I took off but later read you should late in flower. What negative effects might it have?

Spinosad and rain
I applied spinosad tonight and after I finished it started to rain. I used a drop of dawn as well. We even had unheard of tornado warnings. Will I need to reapply? Thanks everyone.

Clean tent before grow (process)
Any suggestions on how to clean / sterilize grow tent etc? Moved some pepper plants from outside into the unused grow tent so they could finish up(worked great) but they had aphids and God know what else from outside. What should I do before I start next grow? Start ETA January.

During this crucial switch between veg to flowering, plants are unhappy about the $2000 stim check. Must appease them, pls help
Switched to 12-12 and damn... that preflowering stretch is no joke. My 3x3 is overflowing with fan leaves. Humidity has gone up on its own since the switch, from ~20-30 to 50-70%. Idk why. Reading about flowering. Any pointers? Start adding flow nutes?Room up,maxed horizontal

Watering practice okay?
When I water, I run 2 gallons of Ro water through every plant. I let them sit and drain for about an hour then I proceed to water them again, but this time with nutes (1100 ppm/6.4 ph). Let them drain, then they go back into the tent. Is that a waste or not? I have no issue.

Can someone help
I know this might sound dumb but how do I probably check my pH levels. I’ve been checking it and it comes to 6.5 but I keep having problems like yellowing leaves and burning leaves and everyone keeps saying it’s a pH problem.

My EC is higher then recommended or I'm reading it wrong. I have been told to add water to my reservoir to lower EC, yet with my well water the EC is already high. Can someone help enlighten me? Using a hydroponic circulating system (DWC with a top feed).

Too fast, too high
So here's the question. The box height is 1.5M. plant is already 75cm + pot size. Apollo-1 is getting closer and closer to the lights, which I don't like. It has 35-40cm left till light panel. Do you recommend to super crop the center, main stem?Or do you have any other solution?
