Hi all! Ok, so, I just need a bit of guidance on feeding during flower, as I'm getting the opposite results to what I was expecting. I've been growing three ladies outdoors for awhile, they were getting on my deck from may 1st to August 1st. During veg, they seemed to be doing fine on their own with just dirt and water, and I think that during the entire veg phase, I only fed them once, with some 3-1-4 liquid vegetable food I'd had from gardening. (A more experienced grower friend of mine said it'd be fine) That feeding was about halfway through vegging. I didn't want to do too much to the plants, they were all super green, bushy, healthy and growing like.. well.... Weeds. Lol. Anyways, August 1st, they went into a 5x5x6 mylar grow tent, and under three 300 watt LED lights from MARS. (I had to go LED, as it was 100f for 2 weeks, and heat in the tent was a huge problem.) I am now on day 19 of flower (all my plants are bagseed, though I suspect the one plant is Purple Kush, as it's hearty as hell, has 11 point fanleaves, and is freakishly huge and durable). While I was away for a week last week, my wife watered and fed them for me. She gave them 2 tablespoons of 2-4-4 bloom food, mixed into a gallon of water, and then have a half gallon to each plant. She fed, skipped a day, fed, skipped 2 days and gave straight water. (PH'd to about 5.8 or 6) that's all. 12 on, 12 off, and that's about all she did. When I came back, some of the leaves had clawed under, and gone dark, other leaves went yellow or a very pale green. Only 1 or 2 fan leaves had burned tips. But one plant, at least half the leaves from the bottom up are turning a pale yellow. So, I'm confused. The clawed leaves look like nitrogen toxicity, (which explains the burned and crispy tips) which I don't understand, because the bloom certs are super low on nitrogen - isn't bloom certs what the plant needs?.. and the yellowing leaves lead me to believe it's not getting enough nutrients, or perhaps again, too much nitrogen? Other than the clawing and yellowing, the plants look healthy. The plant with the worst of the clawing looks "ok".. I'm not impressed with the bud formation after 19 days, but the other two (even the one with yellowing leaves) seem to be doing ok with the flower formation. If it matters, my temps are currently leaking at around 77 during the day and around 60 at night. Humidity seems to hover right around 50%. No signs of mildew, mold, mites, pests or any of that. Thanks for any insights! PS: The photos I've added don't seem to allow captions, so.. The first photo is of the charlie brown lookin' plant, and is the one with the clawed leaves, and is kind of expendable. I don't care much if it goes or not. .. Photo two is the one without as much clawing, but has a LOT of yellow in it. (The close up photo of the leaf is from this one) . Three is of Chuck again (That's the plant's name) and is the clawed one. 4 and 5 is of the Kush (I call it "Spinal Tap", because the leaves go up to 11) and is the really healthy one that's doing great (with some purple pistils), though it has a few fading-to-yellow leaves starting. It's pretty nice, and very photogenic! This is my priority plant.
