Week 3 of veg. On Sunday I watered, 1/4gal per plant with all nutrients from above minus the Kangaroots and Flower Kiss, those were left out. Also added a 3rd LED light to the growing area. The third light jumped the in area temps up to the mid-80s. I added a ceiling vent, 4" with charcoal filter, to vent up into the attic. I had purchased the vent fan and filter ahead of time, knowing I may need them for the heat and the smell. I then moved one of the UV tarps so that it covered the in wall a/c unit, that way I could get cool air into the area. It brought the area down to 75*-77*F during the day and keeps the humidity between 50-55%. On Wednesday I used the Flower Kiss to foliar feed the plants at night after the lights had gone out. I misted the top and bottoms of the leaves. The soil still felt wet just under the first 1/4-1/2" of it, so I continued to hold off on watering. On Friday morning the soil finally felt dry in the top 1" so I watered heavier than normal getting ready for a flush at the end of next week. So I watered 1/2gal per plant, and with nutrients from the 4th week on the schedule wanting to get the nutrients in early before the flush. Give the plants more time to absorb them. On Saturday, at the end of the week, I took the pictures and measured the plant height. Plants were about 28" from the lights so I didn't move the lights yet. Figured I'd move them up once they get within 26".
I think these have nitrogen toxicity, wondering what others think? Yellowing of some leaves, I noticed the clawing in some upper leaves. Buds don't seem to be growing much. Any thoughts?
It's hard to say when the pictures are under that light, try to take pictures under normal lighting for better diagnosis.
From what I can tell in these pictures there's actually a Nitrogen (N) abundance and some Phosphorous(P)/Potassium (K) deficiencies which may also be the cause of your buds' poor development (a picture showing where the leaves yellowing is the worst would really help!)
Hope this helps! Good luck and happy growing :)
Nitrogen Toxicity/Abundance, I believe is my problem. As suggested by BluntZilla in my other question it could be lacking P and K as well. Here are pictures under normal lighting in hopes that someone can help out.
Theyre not showing any signs of other deficiencies/toxicities at the moment just the Nitrogen abundance mentioned.
Yes lower the "Grow" or the Nitrogen source in your fertilizer by about 50% but never stop it completely since it may cause a shock and unnecessary stress!
Keep a close eye at your plants and adjust the fertilizing accordingly! if the color goes back to normal then stay at that diet with a slow increase, and if they start showing deficiencies then increase the nutrients accordingly!
Hope this helps! Good luck and happy growing :)
Great job bro the only thing id change is I would definitely look into getting your self an LEP lamp it would replace all those leds be cheaper to run not as hot as HID but gives you super lumens with the spectrum of led it would have doubled your yield easy and you'd only need one from GAVITA 1930lep
@EasyRaider, definitely man PH and sanitation and pest control are the things that are usually overlooked but stillgreatly important to the plants health almost as much as the light lmao happy growing man keep it
@GACiNATI, That would be great, and probably a great upgrade in the future. I would need two for the coverage space that I would need. Actually, four of them for how I plan to set the room up. As things progress, lights will definitely be upgraded.
Learned a lot from this grow. The nutrient problem was probably more of a pH problem. I just found that my pH meter was a full point off. The buds have been stalled since halfway through flower, and I'm pretty sure pH and nutrient issues were a big problem. Need to make sure to fix those problems for the next grow. Also trying autos for the next run, and a different nutrient line. But yes, lights are a must upgrade.
