Hello, I’m growing 3 clones (fruity pebbles OG, Grandi Guava and white truffle x okie) and just finished up 7 weeks of flowering.
First time growing all 3 and overall it’s went well, except for some sort of issue w/ the White Truffle.
They’ve all gotten the same treatment. You’ll see in the pics there is some burning/yellowing on the tips and all around the edges, with some leaves yellowing in the margins.
Also, the upper section has lightened up with the lower staying darker green.
Initially I thought about light/heat being the cause b/c it’s been crazy hot here (Virginia) and I was pushing them at about 900ppfd…..
I dialed my lights back and raised them a bit…..plus I’ve had to keep the door open just to get my daytime temps into the 77-78f range.
I’ve also considered it could be a K deficiency. The affected leaves certainly present all the symptoms.
Anyhow my grow specs are below and the pics will show both of the other plants that aren’t showing this same issue along with several pics of the problem plant, plus a group shot with the white truffle being in the middle.
Any help is appreciated…..so thanks.
Grow specs:
Medium- Fox farms 70/30 buffered coco
Feed- dry organics
LED Lights- HLG 320 & HLG 150…470W total
Space- 2’x6’ closet with 4” exhaust & passive intake.
I’ve had about a dozen grows with this same setup & recipe and have had very few issues.
Whatta ya think??
