It's quite possible that it's under feeding. This is actually the first time I've checked pH properly so it's not that.
If first time checking how you so sure its not?
I've checked pH on every feed since the start with these plants. I didn't do it before that.
Ok l see now, so not the issue but good place to start, most def caused by bad ph. Causes lockout if low or high.
I've realise that the hard way unfortunately
How do you like the Migro lights?
I was using cfl's, grew some nice plants but the switch to this light has been a different game. The growth is thick, rapid and dense from the very start. I'm sure there's lots of good lights for small grows but this one is well worth the money. The price of electricity used is nothing in comparison to the cfl's. Between €100-€150 per year for the aray I think!
Oh I'm only checking pH of the feed, not the soil. I don't have anything for that. I use the drops. Its made such a difference!
Im back to drops myself, can believe what l see now. Mine started out looking like yours then went downhill fast, if they go yellow and purple and get necro spots, its low ph. At least it was in my case. Guess im happy l got it when l did. Should of listened to that little voice inside my head. Listen to your if it tells you why. Happy growing.
Those are sweet lights, close to top of the line if not at top. Ten year life at least. Good investment. Save a shitload on bulbs.
Back at you man!
