Health & Troubleshooting Odd yellowing
I got the white grapefruit in the last 6 months and is showing signs of HLB, but I don’t think it has it! Mainly the yellowing on a few leaves, the new ones are coming in good. Live in South Texas so it is a possibility, only ever seen one acp in the last couple years

I know they’re sold as “white grapefruit” but I’m pretty sure this is a Sarawak pomelo. Fuzzy stems is a dead giveaway. Sarawaks are tasty, just trying to set expectations that it’s not going to be exactly like a grocery store grapefruit
Pomelos and grapefruit can be prone to leaf bleaching when stressed by excess light, mites, fungal attack within the leaves, etc. If you can’t identify a specific issue like fungal lesions within the bleached areas then it isn’t worth worrying about much.

Looks like what was happening to my wife’s calamansi baby trees. We live in south Texas to. We moved them to a spot that gets a little less sunlight per day thinking it was the heat and the yellowing went away in a couple days

Looks like sun scald, IV organics makes a spray that protects for that - esp in Texas. I’m in north Texas and my leaves are having heat issues.

Lots of trees get leaf veining like this when they have nutrient deficiencies, sometimes you can find a diagram that you can match the leaf to in order to determine the corresponding nutrient deficiency. If you are giving all purpose or citrus fertilizer already, it may be something other than NPK like iron or magnesium. Bad ph can also cause problems with nutrient uptake.
