Well guys and gals, I'm pulling the LED out of flowering. It just can't penetrate the canopy well enough. The tops of the plants look great, as you can see in some of the bud pics, but the underside not so good. My Mangos and Mikados and Afghans and kinda bushy and spread out, so its harder to tell with em, but my Sensi Stars look like compost piles underneather their canopies. The buds look sick, but the colas seem shorter than before, I'm thinking it's because the LEDs just cant get deep enough to give nice thick AND LONG buds.
From the looks of it, LEDs will be best suited for sog and scrog grows, and vegging (which is what I'm putting the leds back to work on). Also Its a big power saver having the leds on vegging 24 7 and having the HPS on only 12 hours a day.
I'll probably sit down and write up a little more about what I've learned growing with LEDs at a bit later date.
That bit of business aside, more about the grow. I've been fighting some nutrient deficiencies as well as spider mites, so I've had my hands full. I started at the mites with a sulfur based pesticide/fungicide as you read about earlier (if you read this thing, thanks if ya do!) which was a terrible idea and didn't work well anyways. After this I went out and got some pyrethrum aerosol spray and started chasing the mites with that. I kept finding more mites here and there though, so thinking I'm missing spots I went out and got neem oil and made up a spray. I soaked every square inch of my plants with that stuff till they were sopping, then I soaked some more. I did this a couple of times with several day inbetween and will continue to do so. I also started feeding neem oil to my flowering plants because they can't get a hose down like the others can (oh, and i'm feeding it to them too). I'm goin all out for complete extermination here. I'll go get some more aerosol and alternate that and neem sprays as well.
As for the nut. def., I believe they were brought about from me using a soilless promix and not adding dolomite lime. I think I have a Calcium and Magnesium def which have also been affecting the uptake of postassium. This combination explained alot to me about how my leaves looked. I started treating a while ago with epsom salts and just got some hydrated lime to add some calcium. Hopefully things will start looking a bit better. I'll keep the results posted.
Well gotta cut this short, gotta decorate the tree!
Pics are as follows Mango, Afghan, then Sensi Star, buds go in that order too with mango starting the bud pics with two pics in a row.
