I used the photone app in order to get these numbers that are pictured below ! I’m going to research them but I’d thought I’d share them anyway.

Phone app PPFD meters can work decently, I use one in my own grow to confirm hanging height, and reference it to the manufacturer stated PPFD for certain hanging heights (MIGROW is good about providing that information.) Your 46 PPFD for the 240 watt LED seems unbelievably low so I would look into that. Make sure the app adjusts for the correct light spectrum/colour of your particular light (eg. 4000k) and keep in mind your phone will measure from the camera on the some side as your screen, and not the one on the back. 200 PPFD for a young seedling, 400-500 for veg, and upwards of 700 in flower are the numbers I aim for. Happy growing!

You also need to have the paper diffuser on top of that light sensor to get accurate numbers. It is pretty accurate tho

What is that?Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6
Increased light intensity to PPFD 600.
This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick.
If it's a light burn, why not on upper leaves?

Force autos to flowerCan you force autos to flower switching to a 12/12 cycle? The canopy was even, but after 6 full weeks only one plant is in flower, I want the others to catch up so they can all be in the same level, I don't want more lateral grow, my tent is full.Week 5

Feeding right after repotting (coco coir).After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200.
I guess EC gets diluted (biggest part of coco coir is new).
Should I increase EC of the feeding water?
I see slower growth but it may as well be due to stress of repotting.Setup. Strain - Autoflowering

Northern Lights Auto, quite short and bushy, fan leaves shielding light - should I defoliate?First time grower with a quite short Northern Lights Auto in week 6. The fan leaves seem to shield a lot of light from the inner leaves, also touching ground. Should I trim the fan leaves? Or should I keep them, since it already seems stressed enough for it's short life…
