My plant is only 2.5 week old, is getting brown/red spots on it's lower leaves and slightly curling leaves, it's just started growing it's 3rd set of true leaves. No other plants in the grow space, using gro+ start compost with added nutrients (says nutes last 4 weeks), No nutrients added yet just plain tap water at room temperature left to stand for 24 hour measuring 6.8-7ph (which I think may be too much?) the grow space is 2x1.5 and light is LED vipraspecter 300watt R300 around 14-16" away from canopy, there's also a small fan blowing around the plant, temperature while lights on is around 27-29degrees Celsius, temp while lights off around 22-24dc. I know it's a deficiency but can't pinpoint which as all the problems that are similar to mine in illustrations are progressive and late stage deficiencies, could it be a humidity problem? as it gets quite dry in the grow space at times, Also when is the best time to transplant and is it safe to transplant root system/compost into buffered Coco? Strain is Royal Cheese. please help!
