Light green tinge

[nLinks12]

Hey my autoflowers are just about to go to flower, and I noticed this light green tinge on the leaf. Can anybody help diagnose the deficiency? I'm growing in coco coir using general hydrophobics tri for nutes.

looks like the beginings of a cal-mag deficiency bump up the cal-mag by 50 PPMs if they don't improve in a couple of days bump it up another 50 PPMs.

I'll try that. Thank you!
