70f-79f and 21%rh-31%rh, with two circulation fans on low- just moving the leaves- exhaust on low (about 100cfm). 20/4 schedule.
The pic shows 3 distict color ranges for this plant- dark green lower fans- normal green in the middle fans and light green/yellowing of the top canopy bud branches.
It's common for plants to have new growth be very light green, but it usually goes away in 24hrs- this is not the case.
I recently moved the fan leaves aside to get the bud sites going which might have been too much.
I recently placed the plant in the overlap space- new light and even though I carefully measure that space, I have no reference points for what works..
The plant is drinking more water at each feeding- every other day.
With all the above in consideration, this is what I'll try.
To the usual water/nutes- I resumed the K but not the single grow dose for the stretch.
The top may be from nutrient deficiency - I gave a full dose of Micronutrients to provide Zinc, Iron etc and some N.
I returned the plant to the overflap area, but 1 1/2" futher away from the CoB.
Stuck a skewer in the soil- to readily see if it's growing.
I resisted the temptation to defoliate, as it may need some nutrients from the lower leaves and those leaves are my barometer during the flower phase!
