So I think I might have a problem with nitrogen deficiency in one of my plants. Here’s some quick context before I get into it:
3x3 tent with two 240w Kingbrite LEDs (measuring with lux meter to hit ~30-40k in veg and ~50-70k in flower). BuildASoil (BAS) nutrient (V 3.0) and mineral (V 2.0) kits in organic living soil – soil base is peat, rice hulls, coarse perlite, pumice, worm castings, four different types of compost (lobster, BAS Malibu, BAS fish, BAS pinto bean). Popped seeds in a seed starting mix in small pots (around volume of a Solo cup) and progressively potted up to final (small pots -> ½ gallon -> 1 gallon -> 3 gallon -> 7 gallon). Used mycos with final transplant. Have kept temps under 80 the whole time, right around 74-77, humidity 40-50%. Watering with spring water (Deer Park 2.5 gallon jugs) ph’D at 7.0 before additions, which have been: FulPower, BAS Big 6 (micronutrients and humic Acid), BAS AgSil, BAS Coconut Powder, BAS Aloe Vera Flakes, BAS Yucca Extract, Fish and Seaweed emulsion, and just now starting to add BAS BuildABloom to waterings. At this point, I’m watering twice a week, about a half-gallon per plant. I have a plastic water bottle that’s right at a quart; drilled a bunch of holes in the cap and I use it as a pseudo watering can. Two of those per plant about every 3-4 days. Plants are mulched with straw and were topdressed with BAS BuildAFlower when they made it to 7G pots, and I also just topdressed yesterday with a blend of BuildAFlower, ground up malted/sprouted barley, and BAS Craft Blend.
So everything has been going GREAT up to this point (day 15 flower, veg for 7.5 weeks), from what I can tell at least. Strains (all Ace Seeds) are Thai Chi, Honduras x Panama, Nepal Jam, and Violeta. The HxP is what’s giving me problems. It’s by far the most vigorous in terms of branching and leaves, and I’m wondering if it hasn’t depleted most of the nutrients in the soil at this point. Over the past couple of weeks, I’ve noticed the HxP yellowing a bit over the entire plant. It seems to be between the leaf margins and older leaves. Just yesterday during my topdressing/watering, I had to prune some dead/dying leaves that were totally yellow and had a few brown spots. These leaves mainly came from the bottom interior, but I can notice that the yellowing seems to be moving up the plant.
The kicker is that everyone else seems to be doing just fine foliage-wise. So I’m not sure why only the HxP would be exhibiting symptoms of N deficiency – unless it has indeed depleted the soil since it’s the largest by far.
I’m just looking for some feedback as to what my problem looks like and, if so, what ya’ll would recommend for a fast-acting organic source of N. I’m thinking blood meal just for that plant for the next couple waterings, if so?
Happy to provide a ton more pics/info if needed, thanks!
Pics are: HxP couple days before switching to flower, overall tent shot couple days before switching to flower, overall tent shot ten days ago, HxP and Thai Chi nine days ago, overall tent shot yesterday, HxP and Thai Chi yesterday, close up of HxP leaves I pruned yesterday.
