Hi Folks,
Hoping for advise; Here's a pic of my Critical-Kush, my first plant, 4th week of bloom. We've had some ups and downs, but I'm happy with the size and bud sites, BUT I'm getting increasingly uncomfortable with her overall yellowness. (some of the shaded leaves are still pretty green) It's under a 600w HID at 75% 14" from the highest point. (too much?). Wednesday I gave her a lot of water to flush it a bit. The run off was measuring high 300s ppm, 5-5.5 pH. I re-nuted with GH trio for 4th week bloom at 1/2 strength, (330 ppm) and put enough on to get lots of run through. Today I took a soil sample and used one of those test-tab kits to check it. pH was about 6.5 (I've done several soil pH tests and they're always about 6.5. Which some people say is correct for ProMix HP). The nitrogen showed about medium, phosphorus and potassium on the high side.
So... should I worry? Should I do anything? Probably another day or two til she needs water.
Thanks for any input!
