bumps on stem rising from bottom towards top

[frankinbeans]

bumps white in appearance on cannabis plants stalk or stem above where the first set of leaves were. they dont look like bug eggs but covering bottom of stem and moving up plant looks healthy

BUMP!

Ive never heard,read or even seen this. Someone out there must surely know.

How bout an update? Has the plant decided to stop growing white bumps? or do you think it was an insect of some kind?

leaves i think on top is lumen burn but the have some green but some yellow spots on some leaves uniformly placed on leaves. older leaves are curld a bit . in soil bumps not as much as a concern as is older leaves have a couple brownish red spot or tanish brown but majority of leaves are decent looking .started out as really indica leaves. now look more like sativa hybrid . humidity ranges from 25 to 55 relative humidity. temp in light period is 74 to 75 and dark cycle runs 63 to 66 plant stoped vertical growth , but its two weeks in flowering or about switched for 3 and 1/2 weeks to a twelve twelve from a16 /8 cycle. no co2 enrichment but remoce air ever 7 mins or 6 . 1000 watts hps powers it with a 65 watt compact flourecent aimed lowe on plant. maybe flush a week or so but is that bad in flowering but i can flush every four days . any recomendation also wondering about trying to take a big 2 ft plant from soil to hrydo plant also been going in flower mode four two weeks. any sugestions?
