Is this possible nutrient burn?
Magic_Chelsea_Crewstarted grow question 6y ago
Sour Kush Day 24 (Coco/perlite) - brown tip appearing on lower fan leaves. I suspect it's nutrient burn. Flushed with 900cc PH neutral water, lot of runoff, PPM was 391 (PPM in 495). Should I cut back on feeding by diluting the nutrient water or by watering less frequently? TY

Lower older leaves is nothing to worry about. Your girl looks pretty happy to me. I would say 495 ppm if your using 5 scale is close to 1.0ec. To me that seems low but things look ok with your girl. Your getting near the point, when the roots engulf the fabric planter, will make you need more water so you dont leave dry spots in the root zone that creates little brown spots half way and near the top of the plant. Make sure you water to you have a lot of runoff. Cheers

My plant has mass nutrient burn on most of the leaves, I've flushed the roots. Is there anything else that can be done to help recovery or is it to late in flower. Also should I remove all the effected leaves or will they still convert energy for the plant? ThanksWeek 13

Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!Week 10

Is this heat light burn? HPS 600w at 20cmIs this light heat burn?? These are all buds at the top of the canopy and they are the ones nearer to the lights. I have 2x600w HPS, one with a cooltube and the other just with the wing. The possibly burnt buds are the ones under the wing (just 20 cm).
