This week has been a lot better! Finally getting the nutrients on track. No burnt tips are appearing on new growth so far. It is getting a little heat stress from being transplanted again and growing closer to the light. Starts out praying for about half the day then slowly droops as the rest of the day progresses. I have been taking it out of the tent and setting in near the window for a few hours in the middle of lights on to minimize the DLI.
What causes the edges of the leaf to yellow like this? It starts on the tip. Tip browns slightly, curls up and then the edges turn yellow and progresses to in between the vien
Seems like Nitrogen Toxicity.
If you are growing in Coco you need to have runoff, measure the runoff, and keep the numbers balanced. If your inflow, as you say, is at 350ppm, you need to make sure your outflow is somewhere around there, if its less then you need to increase feed or increase the times that you are watering aday. If its more then you need to lower your feed.
You ALWAYS need runoff, washing off the previous feed and providing a fresh new one, daily. NEVER follow a wet/dry cycle as it is not soil.
You probably stressed the plant during transplant by washing off the roots etc, this looks like a few things, my first guess is N toxicity, but could also be Mag deficiency. Also another thing to note is that if you used tap water to flush the rootzone you most likely killed all the colonies established from the voodoo juice with chlorine... If you are using Mycorrhizae, fill a container with water and let the chlorine evaporate overnight. I use bottled water from the supermarket :)
Hope this helped :)
@L_Tetragrammaton,
Totally agree! My first time in coco I gave them lots of nuts in the first 3 weeks and they loved it!
Second time I thought I would take it easy on them, watch out not to burn them, I regretted afterwards 😅 They still turned out fine, but I think I could have saved one week of veg.
@Green_Dream, Got everything a little more dialed in on these. Have been fed full line at about 25% since day 3, helps a lot more than you'd think. I usually let them ride the first week with no nutes and the results speak for themselves.
