Added some sand on the top layer. This plant hasn't taken much gnat damage, but i'm still getting a few adults on the cards here and there.
Did a peroxide drench this week, and added plantacillin from Future Harvest to the feed schedule in an attempt to repair any root damage from the larvae or fungus or whatever.
7 weeks is long enough and i feel like ive got the gnats down considerably. So, I'm going to flip to 12-12 so next week will be a flower week.
What do you think caused my sugar leaves and fan leaves to just start dying week 7 flower?
They are rusting from the tips inward at a super fast pace. Effecting the biggest colas at the top first and worst.
What kind of lights are you using? What is the wattage of the light and what is the distance the light is from the actual plant itself.
I had a 600 watt LED fecida light at 18 inchesnand it started butning the tips of my leaves first. It looked exactly like your pictures to be real with you. All i had to do to fix it though was move the light from 18 to 22 inches.
Usually calmag but it also happens if you flush. Most likely cause after that is too much N during flower. Only you, the grower, will know what's most likely of these, but I hope this is enough to solve your issue!
@@Athos, I did give a feeding that was a high ppm around this time. It’s a bit confusing because I was giving the manufacturers recommended doses. And those doses ppm read higher than their own recommended ppm range... maybe you really need to pick and choose which nutes to give and when.
I have 3 other stains getting the same thing and the burn wasn’t that bad or there at all... guess this sdg isn’t as resilient as the others.
Also I learned on this grow I should really be doing a pre flower flush.
