Late Stage Veg Issues

North60 · Sep 4, 2020

Hello folks,
New to the site but have a number of grows under my belt. Can someone tell me what they suspect is my problem with the plants in the attached photos? I’ve been growing outside for over two months and about 8 days ago I noticed the new grow sites appeared a lighter yellow and foliage was stunted. I flushed the plants and started my regular GH feed schedule but I still think there is something up!

Looks like a nutrient issue, check the attached chart against the symptoms and work from there. Could be a combination of dificantcies in particularly Potassium and sulphur look to match, but I notice you have purplish stalks which leans towards sulphur. I'd check the PH and make sure you're not experiencing any lock out and start feeding with an all inclusive fert to cover all the plants needs.

They are outside and currently about 14 hours of daylight. I’m in northern Canada and was also wondering if the cold is becoming an issue since it’s only 4-6 degrees above zero at the lowest point of the day. I’m going flush today.

Thanks. Thinking lockout now. And possibly zinc deficiency on top of other possibilities. Thanks

No flowers yet but I’ve been taking the plants into a garage on some colder nights so it’s getting perhaps a bit more than 14 hours of daylight. I have a grow tent ordered and awaiting arrival so I can flower them
