Seedsman Cream & Cheese CBD / THC 1:1

End of week 10 from seed. About end of week 6 from start of flowering. SO we're at somewhere between day 45 of 12/12 Things are going well still other than my not yet having dialled in the FC-E3000; on one of the plants I have some area of tip burn (mild) and it's now under control as I have raised the heights. That same plant have one plant has what seems like a phosphorus deficiency too, so can only assume lighting AND deficiency as a result. The other two C&C are absolutely fine - all have had the same organic BioBizz nutes so, I have now asked a grower question about this one plant. Thoughts please? As I say, the other two are A-OK! :) Update, thanks to growers for confirming my CalMag suspicions. I have now added more and have also added Alg-A-Mic. Seems my earlier holistic attempts were not enough and she needed more. This C&C certainly seems more calcium sensitive than any of my previous runs. The Blueberry is gone. Totally my fault, letting someone else water her for 9 days was not the best idea and, she was the only one of 7 plants not in a plastic AirPot and the drainage holes, on stand-offs, meant there was a 50mm deep part of the base that built up nutes and ended with her locking out, stressing, ultimately, and seeding. I only noticed too late unfortunately. On examination of the root zone my suspicions were confirmed added to which the lack of development, or at least, what seemed like it, saw the trichs losing that mushroom appearance and looked more like hairs. She was doing so well, too. I have learned an awful lot from her demise but that said there is enough to work with to create or add to the bubble hash pile. The Cream & Cheese, aside of my getting used to the new lighting and them having a bit of a calcium deficiency, is doing well; the buds are coming along well and are fattening, resinous and smell amazing. I have uploaded a few pictures and as ever, thanks for reading. I think we'll see harvest in 3 weeks at this rate!
