Howdy folks. Have a few issues going on that im trying to fix. From all the research ive done, im thinking the yellow coloring is a magnesium Deficiency? Im also clawing. The tips are yellow in the claw. Here are my specs.
Photo: Sunset Sherbert and Gelato
Lights: HLG 260 and Vivosun vs2000
Tap Water @ 6.5 ph
No nutes.
Soil: Coast of Maine Stonington Blend
Time in Veg: 6 weeks
Temps: 80 Humidity 50-60
20 inches from lights
At 6 weeks old you’re ready for nutrients. The lighting makes it difficult to tell but the bottom plant does look a little magnesium deficient.
@BobbyDigital thank you for your reply. The tips have been curled since the 3rd node on the bottom plant with yellowing ( on the tip ) which eventually dried and fell off. I finally got my ph under control a few weeks ago. I was using humbolts nutes for a few weeks, but was told to back off until week 6 or so… here is a picture of the yellowing of those big fan leaves a few weeks ago…
@BobbyDigital also i was advised to start a cal mag foliage feed at lights off
Calmag foliar feed should help since you’re not in flower. It’s a little more instant than water feeding. You should be good to start your feed regimen.
If the leaves are turned up and The Tines are out It looks to me like it’s an initial overwater
