I'm treating that as an NPK deficiency and I'm only seeing it on one plant out of the 5. It's my Tangerine Dream no.4 and...at this point (day 37), it's the most developed. I think it's going to be a keeper. I use biocanna vega and flores in my formula and I've noticed some yellowing with other strains in the past but just needed an adjustment in their feeding schedule to take care of it. I rarely remove any leaves and I'll leave these for the time being. Like I said, this phenotype has flowers that are developing much faster. The other 4 look like each other and are growing in a similar way to most sativas (with a haze influence) I've grown. We're only half way there so we'll see...
Your photo's are .....well.....mind boggling............
Thank you for the detailed response. I am only growing 1 TD under scrog, as opposed to your 5, and value your expanded viewpoint & expertise and that your 24 days ahead of me.
I am also balancing my grow & Bloom nutes as I enter flowering and plan to taper off use of veg nutes, somewhere around week 4 to 5 (depending on what the plant says) to address what I have seen in other grows. Should I be growing the more Sativish of the two Phenotypes you have identified, that may not be necessary.
If I understood you correctly, Once flowering has commenced, #4 is developing faster in it's flowering phase compared to the other four.
Another TD question or 3......... Assuming the other 4 TD's you have are of one phenotype, and #4 is of another, did both phenotypes start to flower approx the same time or was #4 noticeably earlier?
And if you recall, when in 12/12 did they start to show obvious flowering. (my guess would be mid to late, week 3)
And lastly are you counting down from 1st day of 12/12 or from 1st day of actual flower? (knowing the projected 10 week flower cycle is just that.....projected)
I appreciate your sharing of info.
