Running some autos in soilless mix with Grow dots. Plants in question are in 5 gallon sip style buckets. One is mixed with 3 tablespoons and the other at 4 tablespoons of grow dots. Temp is at 80. RH is 50%. CO2 is at 1000 ppm and light is around 1200 ppfd. Plants are dark green and clawing at the tips. Any suggestions on how to correct would be helpful.
Yea N toxicity for sure. N it is pretty water soluble so flushing the media should remove some of the excess. Idk if that will fix it depends of how much N is left in the Grow Dots. I wouldn’t use anymore Recharge for a bit so it doesn’t make any of the Dots more bio available.
I cut the Recharge out this last week thinking with the current problem the plants didnt need it.
If you have a wet shop vacuum, you can really do some serious flushing then run recharge through them. I just put a screen over the drain holes and vacuum. I wonder if it compacts the soil though? This doesn’t really happen anymore since I started using recharge and More reliable nutrients in soil. Maybe someone can tell us if it would compact the soil
Yep, that looks like N toxicity.
I had wondered if this situation could occur with a time-release fertilizer. The issue is, say your plant’s getting too much? How do you UNfertilize for a bit? It looks like your plant went to flowering sooner than the N gave out in the Grow Dots. Not knowing exactly how they work, I’d just guess that if you flush it through a few times you’ll flush out the remainder of the veg-phase nutes. Your lockup doesn’t look TOO far gone, probably fixable at this point.
Obviously too much N. However, wet feet can cause that type of severe claw.
Yes you are correct sir!!!! If you do flush be sure to come in with a correct feeding immediately after to bring that nutrient balance back up. Hang in there!
